So you are going to law school. Several schools have accepted you, and you're considering which to attend. And price is the least reliable of these standards. And, once you pass the bar, where you went is usually far less important than how you practice. But the fact that the U.S. has more than 170 law schools reflects the market for law degrees, not the demand for lawyers.
Law schools are primarily professional schools, and they produce cash for their parent universities.
Add your other monthly expenses, and the oppressive reality of large school debt becomes clear. Plus, when shopping for mortgages, creditors look at your debt to income ratio, and school debts can tip the balance against approval. It is three years of not earning a full-time salary, or contributing to a retirement plan. It is all too easy to overestimate your ability to grab the top grades, and underestimate the competition you will face. That's especially true if you attend a highly ranked school.
