Leaving aside the preposterous rewriting of U.S. history in your comment (the US was never like modern Switzerland, even when it was significantly more homogenous), your goal is not possible with the current size and cultural diversity of the US.
If you want social safety nets, you need a homogeneous culture that stresses (irrationally) not taking advantage of them, thereby making them sustainable.

I came from the other end wherein I believed social safety net and welfares breeds parasitic behavior. But now I've come to believe the benefits of those programs outweigh the negative aspect where a section may starts taking undue advantage of it.
In the absence of such safety nets, I think people will go for more safer bets which make them financially stable as opposed to riskier bets which may bring innovation but could also endanger their livelihood.
