Not really, but some ignorant people might try calling you a commie. I think it is historically a bit different in America, since we lacked much or an official aristocracy, and some of us have notions about anyone having the theoretical opportunity to become ultra-rich, the POTUS, or at least middle-class. Of course, that idea also often gets twisted and used in attempts to shame the poor, or tell people who are critical to shut up and just go get more jobs, which is a flavor of class conflict, it seems to me.
