How do you see individualism as a problem? Our courts have generally upheld free speech rights pretty rigorously, and we a have a pretty strong capitalist ethos, i.e., a right to property.
The worst symptoms of individualism, in my opinion, come mostly from a general American distaste for public programs, like, say, single-payer (government) health care.
Generally, I feel like America has the most problems with a representative democracy. Our winner-take-all system naturally leads to two parties, and public opinion doesn't actually influence policy. Money influences policy. I see that as the big problem, not individualism.
