Simple, because government keeps passing more and more laws that create more ways to become liable. While there may be growing supply of lawyers, there is a growing demand due to this explosive growth of new laws. Stop the government from controlling every inch of our lives, and you will see lawyers getting cheaper.

I also agree with the previous reply that this article only deals with the 10% of lawyers who work in big firms. The other 90% of lawyers that don't work in big firms are out there competing everyday for your business and are charging reasonable rates.
