A demonic phrase by leftists and the Synthetic Left blaming rich people on the problems of capitalism, rather than putting forth a concrete class-based proposal
They falsely believe that taxing the rich will bring about positive change, rather than the idea that we need a proletarian dictatorship as prescribed by Marxism-Leninism
China doesn't eat the rich. They have a normal, calm, rational, "Stalinist" [sic.] Marxist-Leninist government which administers society (boringly) in favor of the commoners, such that the rich do not rule.
The violent mouth-foaming excitement of the American "left" (read: freaks) only makes left-wing class-based politics less appealing to regular American workers who are truckers or farmers or work in warehouses or whatever.
Related to the Luigi Malone type of stuff.
