It comes from the way lower class Americans are treated. The hardship that might be ahead for some otherwise extremely rich and privileged people is actually far less than befalls tens of millions of lower class Americans every single day, and choosing a “move fast and break things” bank is actually a far less “unfair” reason than, say, the circumstances of your birth. The vicious, lifelong message from mainstream society to those most in need has always been “nobody owes anybody anything, that would be socialism”. That’s why those people are angry to see people far better off receive help just because “not doing it would be unfair and hurt them”.
