As opposed to forced retirement accounts you manage yourself? Make no mistake, no sane government would allow for completely voluntary contributions to any sort of pension or superannuation scheme - it'd be setting its country up for a massive economic and social timebomb as the majority of the population put present wants over future needs.

As for investing pensions in the stock market, I'll merely add that in Australia, where we've had superannuation for 20 -odd years, all usually invested in stocks, there were are a large number of people who thought they were going to retire in 2008 (my parents amongst them) who are now still working.

I strongly disagree that retirement accounts should be mandated by the government. If people won't save for retirement, they should understand that the government can't help them. This philosophy that the peon is too stupid and/or undisciplined to manage his own accounts and that the government must protect him from himself is what gets us into huge messes like this in the first place.

I understand this point of view, but at the end of the day, government policy needs to be based on what's going to work out the best for the public. It perhaps goes without saying that there are more than two approaches, but yours is one that I think we can rule out logically.

Psychologically, does it work? In general, if you tell a 22-year-old that in 40-something years he's going to really need some of the money he's making now (even if he feels like he's barely paying his bills), that he absolutely must set aside enough (and invest it wisely, assuming he has the wisdom to do so), will he manage to do it?

From what I understand of human psychology, the answer isn't "yes" nearly enough to make your solution palatable.

It sets up a good learning experience for him when he finally gets to retirement age and finds himself as a greeter in Walmart, but it's way, way too late at that point.

No one wore seatbelts before they were legally required (and still many don't, and many still die because of that dumb decision). People don't, as a rule, have a good grasp of the distant future and/or events that seem unlikely. How many people are still starting smoking, even though it says "cigarettes kill" in big black letters on that first pack they buy?

There are plenty of problems with the US social security system, but removing the safety net entirely to teach a lesson to people who fail to adequately prepare for their old age doesn't feel like a sound approach to me.

And whose idea of "best" do we use? The government is about ensuring a framework of freedom for its citizens to operate within, and if the citizenry refuses to be productive or healthy there's nothing the government can do about it.

Do you support alcohol prohibition? Alcohol leads to much more damage than even smoking from an emotional and psychological perspective.

What if, one day, the government decides that people who buy Japanese cars are a danger to themselves since they are costing the American car companies so much money by refusing to buy home-grown goods? The people just don't have the foresight to understand that buying Honda today means depression throughout Michigan tomorrow. Shouldn't we protect people from that eventuality by ensuring that they only buy domestic vehicles?

How far do we take this? Why do we believe that the politicians have such a heightened sense of foresight and such impeccably unselfish motives? I don't vote for people so they can do my thinking for me, I vote for people who I think will best represent important core principles, like retaining individual free exercise of conscience (like the choice to buy American or foreign cars, even if it will cost Michigan a lot of jobs).

The attitude that we need the government to protect us from our own decisions is in fact extremely dangerous and insidious. Old people survived for thousands of years before the implementation of social security -- if the industrial society doesn't support old people well enough, we have to tweak it so that these things work instead of doing these grotesque hacks of taking > 10% of an average person's salary every year to pay to support your grandpa's RV tour of the US.

We don't use someone's idea of "best" purely based on their opinion. We make changes at a small level, we run studies, we actually find out what works, and stop futzing around with half-baked ideas of what will do what 20 years from now.

This is partly why I hate political discussions as-they-are-played... everyone has such strong opinions based on incredibly tenuous links to actual history, studies, etc.. Just "this is how it is, how it has always been, and if only I were in control I'd have this all tidied up right quick."

Of course I don't support alcohol prohibition. Haven't we tried that? Did it work? Also: we weren't talking about making smoking illegal, just about human psychology, and how people aren't logical. To actually give people better lives requires science, not "more laws" or "fewer laws".

I don't disagree with you on your other examples, generally, but I'll refrain from offering other examples that are obvious in the other direction... it doesn't get us very far.

"I don't vote for people so they can do my thinking for me" -- I half agree with this. I will gladly vote for someone who has thought and researched more deeply on important topics than I have, provided they can explain themselves and advance my own knowledge. In the end we are responsible as citizens for who we elect, so I do agree it's not much use to be snowed by anyone who uses big words or says they have the solutions.

For core principles, though... this is much trickier. Principles, in abstract, are useless. I agree totally with some of my older relatives' politics, when we talk only in terms of principles ("we need better education! critical thinking!"), but when we get into applying the principles we're miles apart.

"Free exercise of conscience", what does that mean in terms of specific issues? We should rely on lynch mobs instead of police? Citizen militias to take out unfair monopolies?

I'm in favor of encouraging responsible citizens who can think critically. I'm not at all convinced that your suggestions (inasmuch as I've seen them) would do that, based on what I know of human psychology.

I also have a suspicion that your idea of what social security payments will cover is a bit overblown. I don't have any living grandparents left, but my father is losing his house and has no medical insurance, in spite of social security.

Somehow, the Federalists have managed to change the conversation from, "should the state provide this service?" to, "should the government provide this service?" I don't quite understand why the state governments should not make their own choices, and people can move to the states that they find have the most acceptable laws to them.

I like the idea of removing power from the federal government in favor of states, but in the case of a service like social security, mobility between states could cause massive issues. State x would not have a safety net, prompting companies and workers to operate there for the tax break. State y, providing a safety net, would be swamped with retirees but not productive workers. Citizens would be hugely incented to game the system. I don't see how it could be sustainable.

If the discrepancies between state policies were large enough, I imagine you'd basically see white flight on a national scale. Essentially, supporting any type of social safety net would be optional for the people with the resources to move out of state. As a result, middle-class and wealthy people would flock to low-tax states without expensive social programs, leaving behind a higher concentration of needy people in the states with the stronger safety nets. What social programs remain would presumably go bankrupt while the nation's wealthiest individuals basked in the glory of their virtually tax-free lifestyles.

That is largely not the case with your neighbors to the north. In Canada only 1/3 of taxes are collected at the federal level, and some of that money is distributed to the provinces to spend (poorer provinces get a larger proportion of payments so they can provide similar services as richer provinces).

While there is some migration to the richest province, that has more to do with jobs related to the oil boom there, and the low taxes there are due to oil revenues.

One possible counterargument to the state-specific approach is that if you have a handful of states that really do well, a majority that do okay, and a few that really screw things up, it's unfair to the residents of the states that chose poorly. They may never be able to move to a better state because the decisions of their current state left them in a financial position too weak to afford life in a different state.

So what do we do with people at the end of their working years, who, through bad luck or bad design, ended up with nothing. Do we stand by and let them suffer and die?

This is not an issue for the government to address. I don't think that people should let them stand by and die, but good governments don't have the powers necessary to give out free money to people they think deserve it. Communities would be expected to handle it in the way most palatable to them. How much more room would Americans have for charity if their paychecks got 50% fatter due to eliminating income and payroll taxation?

There's an interesting argument from Friedrich Hayek (who's usually considered libertarian-leaning) that that approach is actually less pro-individual-liberty than a government safety net is, because it coerces people to stay in collectivist-type communities like ethnic groups, churches, etc., even if they would prefer to leave them, due to the dependence on the safety nets those groups provide. He argues that having a minimal government safety net would give people more freedom to choose their associations within society, since e.g. leaving the Mormon church would no longer mean losing your main safety net.

And do we realize that some may, at that point, turn to crime?

You could devise a means tested welfare for elderly people. There are a lot of perfectly wealthy, perfectly capable people who retire at 60 whatever for no apparent reason other than ss and tax advantaged accounts make it seem like its time. I am a big fan of retirement, and I think safety nets for the disadvantaged are a good idea. I don't think we need a retirement safety net, however, or to make a retirement an entitlement.

The trouble with means testing is that you drain support for the program from the parts of the population with the most political clout. In other words, how long does SS last when rich people get nothing for what they put into it?

I've always viewed Social Security more like catastrophic insurance than a future income stream. What do you get out of insurance? Hopefully, nothing because if you find yourself needing to exercise it, something has not gone according to plan.

I agree with means testing, but think it would have to be something that slowly phased in over a long period, and proportionally to smooth discontinuities so that people could shift their behavior to match expectations.

Actually retirement accounts are demand leakages. For example quantity theory of money gives us MV=PY money * velocity = prices * quantity of goods/services produced. So if money is squirreled away in retirement accounts it is no longer circulating in the economy and in order to maintain the same level of economic activity we have to 'make up' for the lost M. So retirement accounts are a drag on the economy.

Retirement accounts aren't usually held entirely in cash except very near the end. For younger people the bulk would be invested in equity i.e. funding businesses and thus being fed back into the economy.

Its money taken out of circulation that could have otherwise been spend on consumption. Buying IBM stock in my IRA doesn't do much for the economy compared to taking the same funds and buying an IPAD or 100 happy meals.
