I’m thinking it’s because the leftists are all irresponsible, lazy, and self-entitled brats / idiots who need a nanny state to take care of them. It’s the only thing that makes any real sense to me. The reason they hate capitalism is because it requires a lot of work; something they don’t want do (unless its involved with the arts and passion / emotion) so they despise and are jealous of us hard-working when we succeed thinking in collective socialistic thug groupthink terms that the capitalist needs to fork over some of that cash. Jealousy and self-entitlement are the socialist’s driving forces.
I believe it is narcissism (writ large).
The overweening compulsion to feel good about themselves, even superior! - blinds them to the results their corrosive ideology produces.
