The government is made of people, and people, by and large, want to do the right thing and improve society. But yes, there's a lot of corruption. With power comes the ability to make money from special interests. But we'd be much worse off without the government. We'd have no protection from crime, no infrastructure, no mass cooperation through contracts, employment, governmental organization, etc. There'd be no civilization. So the government deserves some level of trust and support from its citizens. And where it fails, it's our duty to try to correct it. A much worse thing to be wary of and that people seem to have delusional faith in is corporations.
