It's one of those funny things that people never seem to notice. We believe in competition and a marketplace but look past the obvious monopolies!
I dunno if this is the only way to solve the problem...but, right now, our legal system strongly favors the wealthy (this can be seen in convictions and sentences of rich folks vs. poor folks). Some of the disparity is legislative (i.e. cocaine possession having a vastly shorter sentence than crack), but a lot of it is simply in the difference in quality of representation.
Not to mention that when it comes to lawsuits, only rich people have the money to play at those games. Which may be why the worst polluters always seem to end up in the backyards of poor people. Rich people would sue them out of existence. Poor people have no recourse, unless some ambulance chaser sees an opportunity for a class action suit (where he'll make millions and the people affected will get a few measly bucks). I dunno if removing the bar as an impediment to representing someone in court would solve this problem (probably wouldn't; there are lots of things stacked against poor people in our court system, not just the lack of affordable representation), but it might be a start.
Whew...I didn't know I had such strong feelings on this issue until I started ranting about it. I guess that's how a lot of folks are...never thinking about the bar (or the medical association), or what unintended consequences it might have.
