Legal Careers are so unpredictable, so it's hard to give great advice.
Lawyer starting salaries have been dropping since 2007, and the median
starting salary for the class of 2010 was $63,000 for those who were working full time and reported a number
. So that means the median starting salary is much lower. http://www.nalp.org/classof2010_salpressrel
For those who reported in 2008, the bimodal distribution is pretty clear, which means a significant percentage of graduates make under 50,000. And you have to figure that a large percentage of those who do not report their salary are not making good money. http://abovethelaw.com/2010/05/nalp-2010-nalp-executive-director-james-leipold-talks-to-the-lost-generation/bi-modal-salary-distribution-curve/
Lawyers do have pretty good income potential over the long term, though.http://www.abajournal.com/magazine/article/what_americas_lawyers_earn/
So when considering law, it really comes down to some heavy introspection. 1) Will you do well academically, 2) will you aggressively and effectively network, and 3) will you like working as a lawyer?
The sad thing is that #1 is unpredictable, #2 is generally overestimated by people, and #3 is almost impossible to know because you can't predict what job you'll end up in. I absolutely love white collar criminal defense and construction litigation, but I hate family law, collections, and probate. I had to take a job where I primarily do family law and collections, and I'd rather be outside digging ditches.
Financially though, I still believe the law is a good investment. If you take out 120,000 in loans, you'll probably be paying loan payments of $10,800 a year for 25 years. I think the median lawyer from the schools you mention will probably make 10k a year more than the median bachelor's degree holder or the median MPA or MBA from the schools you mention.
Paralegal work isn't bad, but there is a low income ceiling. You can
probably find a good job for 50k a year with good hours, but you'll never make much more than that (adjusted for inflation).
