Bernie only released one atypical year, so yeah, those who understand tax forms understand that in, say the early 2000s, he paid a much higher effective federal rate because he was still paying SS then.
The percentage is not as important as the bottom line you say.. and then go o to =talk about percentages, while getting the numbers wrong-- for someone touting Googling, it's strange that you didn't bother to Google away.
Here's something to Google while your at it-- polls of "happiest" citizens... guess which nation is in the top 5 pretty much every time.
But in any case, Denmark is just a straw man, as what you really should be looking at is US taxes, say in the 1960s and 1970s and even (gasp) under Reagan in the 1980s.
then you trot out the old Hoary "the rich will leave" argument, when that number is of course you (gasp) assuming, with no numbers and little thought on it other than the sound bite. Will the Kochs give up their US citizenship? Doubtful.
And then you basically trot out the "the rich won't invest so they can avoid capital gains taxes", except with an even more backward twist-- do you really think stock speculation creates jobs? The usual argument of the defender of the rich is that they won't invest and create jobs if their taxes are raised .. which is just silly, lol, if one thinks for half a moment-- as we saw in the 1950s and 1960s, when faced with higher tax rates the wealthy invested MORE than now, in deductible business infrastructure, which creates jobs. Because they face such LOW taxes now they have no incentive to create jobs with deductible-from-income investment, so they speculate on stocks and stash their low-taxed profits in the Caymans.
Would there be a net gain in revenue-- absolutely, because of the JOBS (new taxpayers) created.
