People are being hyperbolic when they say you need to go t-5 or bust. You don't. You can get a perfectly respectable legal education at many law schools in the nation. Don't fall prey to the manufactured prestige of some programs, do not be lured by a certain status a school or program may say they have.
You're right about it being manufactured prestige. If you go to any law school you're likely to get about the same education as what you'd get at a top 5 school. But the point remains, the manufactured prestige DOES dictate your job prospects, even though you learned the same thing. Do a google search on whether or not the prestige matters and you will be VERY hard press to find a source that contradicts that sentiment.
If you go to a middle of the pack law school you can get a job but only if you graduate at the very top of your class or if you happen to have really good connections. I'm talking about the kind of connections where you already know who you'll work for before you even start law school.
