Well I think America is splitting into two cultures. One is the traditonal American culture, epitomized by perhaps Rocky but more so by hardwoking, vituous self-reliant people. This is the culture that built American greatness.
The other, newer culture is epitomized by Obama’s aunt - opportunistic parasites who want to enjoy the wealth created by the old culture and who expect the “system” to take care of them. As America is overrun with immigrants (and some native-born) with this expectation (just as the Roman Republic was) it will be increasingly hard to maintain he old culture.
It would be “easy” to destroy that second culture, actually.
Perhaps “simple” would be a better word, because “it ain’t gonna be easy”.
Simply remove their entitlements. When they can no longer eat without working, that “culture” of dependence and entitlement goes away pretty quickly, within a couple of generations.
