God forbid, maybe what counts for being a good lawyer and being successful is more than just the name of your school on your resume. We certainly would not want to grapple with the fact that some people, regardless of where they go to school, just will not make good lawyers/make a lot of money. People here are adults (well most). Let them make their own decisions on where to go to school, let them make their own success or failure. I got enough to worry about on my own without putting so much thought into what someone else is doing with their lives.
I have to agree with Matthies on this one. The person that is encouraging me the most to go to law school graduated from a tier 4. He's a self employed trial lawyer now and 10 years into his career and he's doing quite well for himself. He's a workaholic but he enjoys his downtime too. If you market yourself right, in the right market, and you know your specialty there is no reason why you can't do well for yourself even if you go to a tier 4.
