Also, you must be thinking of your marginal rate being 33% - your federal taxes should be under 20% of your income at $170k, even if filing as single. In Germany, your tax rate would be about 27%.
33% is not a marginal rate, it's an effective tax rate (filing jointly) including payroll taxes which are deducted from my wages, I mentioned it. Also we have a state tax in MA which is also included in 33%.
In any case there are other taxes too (e.g. gas excise, vehicle excise, property tax etc.), so I'm not trying to compare the whole tax burden, that would be too much for HN. But regarding payroll taxes -- they are pretty close even if you consider VAT, certainly not a "lot less", it's a myth propagated by politicians. So the question is: we pay (almost) "welfare state" taxes, where is my part of a welfare state?
All those other taxes exist in Germany too, by the way, and are much higher.
No, I'm not getting "welfare state" benefits, I'm getting a pretty crappy medical service for a price which is waaay higher than in Germany. And if I lose my job I will be paying 2K/month + copays and co-insurances, not mentioning deductibles, unlike in Germany. And God forbids you get into a hospital without insurance, your jaw will drop to the floor when you see the bill.
Have you ever been in the Boston subway? Compare it with almost any city in Europe, hell, even with Montreal. Tell me which welfare state has subways like Boston or NYC? Commuter rail like in Boston? NYC commuter rail is a bit better, but still is not even close to German railways.
And all of the above we get for taxes which are very similar to Germany. No, they are not much lower, it's something with your math. And in absolute value we pay waaay more than in Germany given higher salaries.
