Basically what saucetenuto said.
In the USA at least, much of our government could function nearly the same regardless of if our market system is completely laissez-faire capitalism, or hardcore communist. In fact, you could argue that government and its' systems, like the judicial system should be completely devoid of any possibility for profit motives. Since, as saucetenuto states, those undermine the system.
Now, I don't want to get into an argument about whether good lawyers deserve to get paid better than bad lawyers, etc. But I don't think I'd want to meet the person who sees the justice inequality between rich and poor defendants and thinks "All is as it should be."
