The University of San Francisco has been accredited since 1935. There are a lot of schools through which there are pretty good job prospects. You can make good money without working in a big law firm. My friend's Dad went to Southwestern (which is by no means a national school), but he makes a lot of money. A lot depends on how hard you work and the chances that you are willing to take. Sometimes working for a really small firm pays off, because you can make a greater share of the profits once business picks up.
Another way of thinking about it is that 3rd and 4th tier schools (although usually expensive-especially in California) make it possible for people with poor grades and LSAT scores to still go to law school. Those schools aren't prestigious, but if you have the money then you can become a lawyer.
