It was a few years back, but I did some calculating on taking ALL the wealth of America's billionaires.
It came up to about 4 or 5 trillion dollars, at the time enough to run the govt for about a year and a half, and cover at the time maybe 3 years of the deficits we were running in the Obama admin.
I went down to millionaires and you could fund the govt for maybe 4 years, and 7 years of deficits.
These lefty nutloons just don't get it. As much wealth as there is in America, govt spending just dwarfs that. You can't tax income enough, and even if you outright confiscated and liquidated existing wealth, there isn't enough in the rest of the world to pay full price for it.
