I hate to sound like a populist, but for goodness sake some perspective is necessary.
Spending is just deferred taxation, and spending keeps going up. Yes, after adjusting for population and inflation: http://www.usgovernmentspending.com/spending_chart_1970_2017...
It peaked at 94% during WW2, but even absent of any wars, it was significantly higher than it is now (35%).
It was even worse once you work out how much more progressive our tax is now than it used to be. In 1982, you were paying 50% federal tax on all income above $106K (about $200K in today's dollars). Now the top tax rate doesn't even kick in until after $388K.
People today are paying historically low tax rates mostly because of the Republican's cynical attempt to "starve the beast" in order to reduce spending - which I might add is entirely backwards as it gives everyone what they want and no one feels any pain. If they really wanted to reduce spending, they'd force tax raises so everyone felt the consequences of every new government program.
(Obviously, the above is too simplistic to actually rely upon, but that's how corporate taxes reduce investor returns, effectively resulting in double taxation in many people's mind, including my own. I still believe that's part of the reason LTCG are and should be taxed at a lower rate than ordinary income.)
Saverin's paying 15%. Sounds like the goal is met.
I'm not by any stretch of the imagination against people making money, but you have an obligation to pay it forward to the society that enabled you to do it. Defending this sort of behavior smacks of the wealth-worshipper disease and there's not a lot worse than that.
What would be satisfactory? That he paid based on the ipo price? What the stock is worth at the end of ipo day (likely inflated)? What it's worth a year from now? 5 years? 10 years? What would be fair?
If I understand the situation correctly. He is basically going to be allowed to pay capital gains on $X after selling for something like $10X, making his rate more like 1.5%.
If you want to continue the discussion, do you think you could try to do without the personal attacks? They're very irritating and completely uncalled for here.
