Nobody got elected by campaigning on a platform of cutting taxes for the super-rich. It was a deceit. They typically campaign on cutting taxes for the middle class, but then after elected, the super-rich get massive cuts and the middle class gets a slight cut. And the last time they did it, they made the middle class tax cut temporary, while the one for the rich is permanent.TREMENDOUS UPPER-INCOME WEALTH IN AMERICA
I think, rather, that they US must get its upper-income tax back to where it was a long, long time ago.
Have a look at the history of individual income-taxation in the US here
Note that in 1918 the tax-rate was as high as 80% in the US. That was corrected by artful work on the part of the rich to change the political-weights in Congress! Almost immediately, the rates started their decent and reached bottom around 1925 at around 25%.
Then UP GO TAXES again in 1932 and they remain constant till 1964. Who was PotUS that year? JFK who had just enough time in the presidency to bring them down - to please his father who helped fund his election-campaign!
The rest of that history shows aptly a decline in upper-income taxation that was undertaken by a series of Replicant-presidencies - all elected by "we-the-sheeple". (Obviously enamoured of the rich-'n-famous!)
So, let's stop belaboring the issue! The lower income-taxation of the rich and super-rich generating their enormous wealth is OUR MAKING. That is, successive serious reductions by Replicant-presidents we voted into office! Which has led to the gross-mistake of tremendous upper-income wealth today in the US.
WE THE SHEEPLE LET IT HAPPEN and it can become undone only by getting rid of the Electoral College that perpetuates Replicant-control of either the HofR or the Senate or both. Either one will and can block the other on taxation-matters!
Which is why Europeans refused to copy taxwise what was happening in the US as they restructured themselves after WW2 ... !
Bernie had the right idea, and a LOT of support, but he couldn't get past one word. The S-word. Oh, he hugely took the pox off the S-word, but the hard right was unswayed. They still equate socialism with communism and think it means the government is going to 'control every aspect of their life' if they vote to tax the super-rich. Nice bit of repackaging there by the adept right, masters of propaganda.
