I don't even own a house!
Joking aside, there's a reason why investment income is taxed lower, and it benefits the middle class too. The money they make working one year gets taxed 20-30%, if they intelligently choose to save some of that and invest it, do you want to tax the yield of that the 2nd go around at 20-30% again? Don't you think the tax rate on investment yield, which affects net return, influences their decision to save vs. spend? Most countries in the world have lower rates for investment income.
I'm not entirely against some level of inheritance tax though, just needs to have some thought put into it, since there are both economic and moral aspects. The answer for the tax system is not simply 'more from the 1%', the how matters greatly.
P.S. In a sense the US government was a 40% partner in everything GS or any other IB ever bought for me or their thousands of other clients on thousands of occasions, because its booked as a cost and comes out of their bottom line, therefore reduces their tax burden in $ terms. (Or maybe GS somehow runs a P&L loss, not bothered to check)
