(Over) Simplified:

It's primarily lawyers (or at least, law school graduates) that make the laws, and they are also the ones profiting from ridiculous cases. It's up to lawyers to fix the mess that the lawyers made, that the lawyers are profiting from.

Obviously, only lawyers are happy with the situation.

As I said, this is a simplification. But it is too close to the truth for most people, and so most people dislike lawyers for "screwing things up".
