The $100K annual income level is not "stupid". What is, however, both stupid and unfair is the fact that effective tax-rates above $100K per year (with a clever accountant) are about 15/20% per year.
Fairness in taxation is mathematically progressive, and progressive taxation should look like this:
Except the percentages vertically should rise to 100%, not 35%. Were that the case, a lot fewer selfish "banksters" on Wall Street would be tempted to make a quick megabuck as they did with the Toxic Waste Mess.
Which is what provoked the Great Recession in 2010 - now six-long-years old.
That which I find "stupid" is the fact that household incomes above $100k are taxed at a flat-rate of less than 30% (and often even less if a number of legal reductions can be made). The effective rate above 100K is perhaps in the range of 15/20%. (Remember Romney in 2010 when he foolishly admitted that he had paid only 14% in income-taxes? That probably cost him the election.*)
About 10% of households above the $100K Income Level garner nearly half the total income generated by the economy, as shown by economists Piketty & Saez
here. It is precisely this group therefore that should be paying far higher taxes, which would be the case were tax-levels progressive.
But, they aren't, so the rest of us are victims of the biggest tax rip-off in history ...
No income-tax on earth does or should. What difference do skills mean to tax-authorities? Nothing.
Really? Go have a look at the US budget - then tell me how the US is going to obtain the money to pay for your retirement pension or the national debt.
Taxation is unavoidable ...
*And the fact that the Dork hasn't paid taxes in perhaps a decade or so doesn't seem to bother anybody ... ?
