America is home to thousands if not millions of volunteer groups, social change movements, debates and university studies on these sorts of situations. There isn't any sort of central government ministry dealing with stuff like this, but large independent swathes of society do try to work to establish where these problems come from, and how best to deal with them.

If anything, Americans would suffer more from fatigue by being bombarded with tons of national social issues to genuinely worry about and try to work against, rather than remaining in denial about them.
