Also, if you are going to mention the opportunity cost of defense spending, then I think we should also carefully assess the opportunity cost of not securing the world with american power and returning to a world without a dominant unipolar power, as a multipolar world seems much more prone to conflict.

Having the government hire people to dig holes and fill them back in, in that specific context, was better than them being unemployed. Doing useless work wasn't productive, but neither was being unemployed, so that's a wash. Meanwhile having money in their pockets meant they had money to spend, and then they paid other people to do things that actually were useful. A net gain against the status quo.

But even then it was a false dichotomy, and now it's even worse. The false dichotomy is that the options are to do nothing or to pay people to do something useless. There is a third option -- pay them to something useful. That's better than either of the other two.

Today it's even worse, because unemployment is very low. People already have jobs. They're already getting paid, and most of the work they're doing is already productive. In that context make-work jobs don't just not help, they actively reduce productivity, because people get paid either way and you're just changing what kind of work they do. If they would have been doing productive work and you convert them to digging holes and filling them back in, you're making things worse, not better.

In the 1700s UK and Ireland, many rich people thought charity in the form of hand-outs was a bad idea and reward without labour was bad for character [1]. So some rich people who wanted to help the poor would hire them for things like building 'follies', extravagant decorative buildings and roads to nowhere. Having famine victims earn food with hard labour went about as well as you would imagine.

But of course they do, because if they didn't then they could just take the "free" money and still volunteer to do the useless work. Maybe some people like digging holes and filling them back in -- it's good exercise.

But anybody who can think of anything more productive to do with their time is then given the option to choose that instead.

This is happening in practice. There are lots of popular jobs where people will put up with anything to get the job. Game developers routinely have "crunch time" but they don't quit as a result. Some even think it's a bonus because they get to spend more time at their dream job.

But this just becomes "zomg govt so dumb pays ppl to dig holes lol, communism fail".

If you think there was a false dichotomy then you never understood Keynesian gold digging. Just read Keynes' quote:

>If the Treasury were to fill old bottles with banknotes, bury them at suitable depths in disused coalmines which are then filled up to the surface with town rubbish, and leave it to private enterprise on well-tried principles of laissez-faire to dig the notes up again… the note-bearing territory), there need be no more unemployment and, with the help of the repercussions, the real income of the community, and its capital wealth also, would probably become a good deal greater than it actually is. It would, indeed, be more sensible to build houses and the like; but if there are political and practical difficulties in the way of this, the above would be better than nothing.

The emphasis should be on the last sentence. Do you really think nobody thought of something as simple as "pay them to do something useful"? The reality is that politically there are only two acceptable ways to spend money. Either you spend the money with an expectation of profit (Investing) or you spend it with the expectation of losing it entirely (Welfare). Once the government uses that money to subsidize a money losing state owned company, private interests will raise their voice and heavily criticize the unfair competition and use it as an excuse for layoffs or pay cuts. Again, just read Keynes' quote

>It is curious how common sense, wriggling for an escape from absurd conclusions, has been apt to reach a preference for wholly 'wasteful' forms of loan expenditure rather than for partly wasteful forms, which, because they are not wholly wasteful, tend to be judged on strict 'business' principles. For example, unemployment relief financed by loans is more readily accepted than the financing of improvements at a charge below the current rate of interest; whilst the form of digging holes in the ground known as gold-mining, which not only adds nothing whatever to the real wealth of the world but involves the disutility of labour, is the most acceptable of all solutions."

Gold digging has always been about finding a solution that people will vote for. It has never been about the most efficient way of restarting an economy.

The issue is that it's claiming to be a reductio ad absurdum -- paying people to do useless things is an improvement, therefore paying them to do something is useful is even better than that.

But the first claim only holds under conditions of high unemployment, and if it doesn't hold then it doesn't prove the second one. Paying people to do "something useful" is better than having them not get paid and not do anything useful, but that doesn't prove that it's better than what they would be doing in the alternative, which could be getting paid the same to do something even better.

Proving that your something is better than nothing doesn't get you out of proving that it's better than the status quo, unless the status quo is people doing nothing. And even then it's only if people are actually doing nothing, not just not having a job and using them time to learn a new skill or start a business that doesn't produce revenue yet or do volunteer work etc.

> The reality is that politically there are only two acceptable ways to spend money. Either you spend the money with an expectation of profit (Investing) or you spend it with the expectation of losing it entirely (Welfare).

The only thing governments should spend money on is in the category of welfare. Having roads or subways paid for with taxes and not fares is "welfare" because it's not profitable. But "welfare" can increase efficiency because the existence of transportation benefits everyone (even indirect users), and the expense is dominated by fixed costs which makes charging usage fees inefficiently discourage use of a resource that has been paid for regardless, and fare collection itself is a major cost center that can be eliminated when they're funded through taxes.

If something is profitable then you don't need the government to do it because private companies will do it anyway. The only way out of that is to start classifying welfare as investment when its positive externalities exceed its costs. But by that point the only categories you're left with is "profit" and "waste", because welfare programs that cost more than the benefits they produce shouldn't exist either.

> Once the government uses that money to subsidize a money losing state owned company, private interests will raise their voice and heavily criticize the unfair competition and use it as an excuse for layoffs or pay cuts.

If your town wanted to install municipal fiber, Comcast would whinge about it so hard you could hear it from space, which is the primary reason it hasn't already happened in most places. But just because hiring people to build a fiber network would be productive and we can't do that as a result of lobbying, doesn't prove that hiring people to do some less useful thing would also be productive.

But this just becomes "zomg govt so dumb pays ppl to dig holes lol, communism fail".

America had military teams operating in 134 different countries in 2014[1]. Does that really indicates a unipolar power that's less prone to conflict?

Put simply, war is never good, it damages even the victors, and, the necessity of being prepared for it should not blind us to its costs.

We all come from the same family, at the end of the day. Albeit a particularly contentious one ;).

Of course, but I'll be damned if I let my brother sock my mother in the nose just because he's family. Not that I'm walking around looking for a fight. On the contrary.

And if it were my specific responsibility to protect people, it would be foolish for me to become out of shape, unequipped, sloppy, and inattentive. Staying prepared has "costs", of course. That doesn't mean every minute of cardio, training session, or watchful minute is a waste. It would be if someone else already fulfilled that responsibility or if I were egregiously overpreparing or mispreparing somehow.

Loads of research finds its way back into civilian hands and does good for society, and it's hard to know what'll be useful and what won't. But churning out the same old missiles and tanks that we'll never use is money that could've been better invested in infrastructure or pretty much anything else.

Much military spending has direct value as surplus goods, scientific advancement, humanitarian support, and patronage for domestic skilled industry. Maybe those benefits, and others, do not justify the expenditures in all cases, but it's far from a "perfect" waste of economic output.

There is nothing good about unipolar power. If ran unchecked it becomes an fucking arm twisting thug ready to go to conflict every time it does not like something. Luckily while most powerful at the moment it is far from being unipolar (not for the lack of trying).

War is what happens when two or more groups of people find no other way to resolve a conflict other than by killong the other party's people and destroying their belongings until they give in.

Murder is intentional killing of a person outside of acceptable and legal contexts (such as self defense).

We don’t need to accept massive DoD funding of violent undertakings that end up killing millions simply for the meager benefits we get as a side effect sometimes.

The U.S. military commissioned and deployed GPS to configure the clocks and weapons systems required to hold off the hostile and ignorant powers of the world.

Also I don’t think Russia, China, Iran, etc, are any less ignorant than the US. Differently ignorant, maybe ;). Which is not to give those countries a pass.

America has used the promise of force to uphold a status quo that most people can get on board with, one which doesn't really warrant revolt. The CCP probably will not accomplish anything like that, if we are ever so damned that they become the hegemon; in that case we might as well have just surrendered to the Nazis.
