Not all progress is good. Its best made in measured doses.
Life is good. Sure there are problems, but they can be solved without completely changing the system. Better laws and regulations, going after those abusing the system, that sort if thing.
Also the only alternative presented is communism. And historcally, whats been advertised as communism has lead to a 100 million deaths, the oppression of everyone else involved, and generally bad shit. (No, Im not arguing about what is true communism)
