Yup, the problem is firmly the system, but suggesting a worldwide change to socialism/communism is less “palatable” and believable by the average person.
So “eat the rich” is a decent compromise for a comment not intended to approach any sort of complex answer, while still being a move in a better direction than suggesting things to continue as they are.
Redistributing the wealth of billionaires is already part of a good structural change, it’ll remove from them power they’d use to continue the exploitation of the people. You can substitute “crush” by destitute and incarcerate them if you’d prefer, as long as the wealth isn’t on the hands of the few anymore.
