Let's remember that, strictly speaking, it's champerty that brings the courts to the little guy.  Think about the typical car accident victim - you can be sure, most of the time, that his attorney is being paid on a contingency basis.  In other words, the attorney doesn't get paid unless the plaintiff gets an award at trial.  The attorney takes a big chance that she won't get paid for her time and effort, and the plaintiff/victim gets a shot at compensation without taking the big financial risk of losing.  This is also beneficial to the system - a contingency fee attorney won't take a case unless it's a pretty strong one, because it otherwise wouldn't be worth the almost certain financial loss.
