You didn't? It's not hard information to come across...
Actually, it is. And the information changes.
When I finished undergrad, I did a lengthy analysis of the benefits of going to law school. Statistical information put out by the Bureau of Labor and Statistics and the American Bar Association put a high probability of employment with a median starting salary of $87,600, and an overall median salary of $157,000 based on my geographic location. Tuition, fees, and books ran at ~$31k per year. You could get a job working 15-20 hours a week during the school year that paid $14/hr your first year, up to $25/hr your last year. Increasing hours to 40 hours during the summer. When I did the math, I could leave law school with approximately $70k in debt with a salary of $87k. Not a bad trade off. All numbers put out by 3 competing law schools and backed up by the ABA and the BLS. I had an offer at the time to become a police officer. Starting salary of $29k. Law school put a difference of $58k pre-tax on the table. Over a 20 year working career, that's $1.16M (not counting for raises on either career path). Less loans of $70k, there's a benefit of $1.09M to going to law school. Or at least that's the math.
Then 2008 happened. Big law fired a third of their associates. They flooded the marketplace, took all the entry level jobs. Pushed median starting salary down. Pushed employment rates down. Some couldn't find jobs and took unpaid internships to fill resume gaps.
What did that mean? No paid jobs during law school. No paid jobs (and not many unpaid internships) during summer. Rent still became due. You still had to eat. If you backed out, you still had $30k+ in debt and no degree to pay for it. Then the school decides to jump tuition from $27k to $34k to $38k. Not like you can back out now. Push through the end and hope the time you spend in school gives you time for the economy to bounce back.
Only it didn't. When I graduated, starting salaries in the $40k range were not uncommon. 3% of my graduating class had job offers at graduation. I was one of the lucky few.
Average tuition, fees, books, expenses at $34k per year, plus $15k to live off in loans per year, leaves $147k in debt. Not counting undergrad. Paying for it off a $40k salary.
Yeah, you could cut that $15k annual living expense number down, but not too far.
Real easy to point a finger of blame. But life happens along the way.
