I.D. a quote about the "Working Classes"?

Please pardon me posting this, but this has been stuck in my brain all evening…and it itches.

I half remember a quote that went something like, “There are three kinds of people in the ‘working class.’ The kind that thinks the world owes them something because of their situation, the kind that believes in working hard and honestly, and the kind that does everything they can to find a way out of their station in life.”

I may have gotten some of the wording wrong, but I think that that’s the jist of it. And I have no idea who’s supposed to have said it, aside from a vague feeling that it might have been J. Michael Straczynski, and I know that can’t be right. Can anyone help?
Well, thanks for your time,

Aw jeez…I didn’t DREAM it, did I?
