Yeah, I think it is official leftist dogma, which isn't really a bad thing (I prefer it to rightist dogma at least). But, as Nietzsche reminds us, every dogma exists to help effect a subconscious will to power, whether you're a social worker or a capitalist.
From your second paragraph (with "that is probably related to not being around that particular mindset"), I think we all agree on the value of enculturation in a person's success, though we are all different in our connotations. I think he is playing "let's call a spade a spade" in his post.
I also don't think you are advocating fight the rich, but I do think you are channeling arguments that others have made uncritically. It's ok, we all do it, all the time.
There's not many original ideas around regarding this stuff, and even fewer plausible explanations, I'm afraid most people will usually sound like they're repeating other peoples' ideas.
My point is more that people repeat other people ideas uncritically. Then we have lack of progress.
While I was criticizing you for it, in good faith, I do it myself all the time. It isn't that you should stop repeating other people's ideas, just that you (and I) should be in the habit of wondering "where did that come from? what does it imply that I might not be thinking of? who benefits by the propagation of that idea?" etc
In the case of the leftist dogma, I think there are incorrect assumptions about (1) resentment, (2) cultural diffusion, and (3) fault. Even if you don't share them when you examine it, that argument has a lot of baggage.
