A Few Questions for Leftists

I sometimes wonder how so many pro-government people can seem to recognize corruption, abuse of power and money, etc. when it comes to rich CEO's, but cannot see the corruption, abuse of power and money, etc. when it comes to rich government officials. As far as I can tell, the only difference is that they don't like the fact that the CEO is rich from having engaged in trade with them, but they do like the fact that the politician is rich from having forcibly taken our money from us. They support what amounts to theft (try to do the same thing as the government and see what happens to you; also, try not to pay your taxes, and see what happens to you); I support free exchange between cooperating, free people. How can somebody be in favor of involuntary exchange, but be "morally" opposed to voluntary exchange?
