To paraphrase Stalin, the lefties have no money, and they have no batallions. All they have is an idea, and that idea is anathema to those with both batallions and bucks. As for your closing comment, I can find something to agree with, but I can add my own twist to it.

In a brutal and unforgiving meritocracy, those who fail are forced to accept that perhaps they are lacking in merit. It is much easier to blame their failure on those they can accuse of rigging the game. Leftists blame those who succeed for manipulating the system so no one else can play. Rightists blame those opposed to the system or outside of it for sabotaging it so the truly meritorious (them) cannot prevail. Envy is not restricted to the left, everyone is willing to substitute the "other" for their own shortcomings. The Reds had their bourgoise capitalist roaders, the Nazis had their Jews. Even the rhetoric is surprisingly similar.
