The system that we know of today is broken. It may seem that everything is working fine and that everyone is getting along fine, but the fact is that our system is broken and damaged at every level in society. The congress is corrupt to some extent because there are lobbyists who pay people off, to some extent even the senators and representative to speak on behalf of corporations.
No, the System is not broken, because American society functions quite well. The best society would be governed by a wise philosopher-king, but since those are hard to find in real life, the American system of democracy works well to protect private property interests and bring offenders to justice. Americans are kind and generous, and our country is quite good.
