Maybe because they are not under taxed. I hardly consider a married couple making $250,000 a year the “filthy rich”.
If Warren Buffet thinks he’s under taxed he can certainly cough up more of his own money for taxes.
I wouldn’t either; probably more like the working rich like doctors, professionals and business people. The Warren Buffets, Soros’, and their ilk. I can’t defend them with the same zeal you do.
