The quick answer is that nationally law school's graduate 45,000 people per year, but the job market only has 25,000 positions. That means slightly less than half can't get a job. How that stacks out varies, but shitty schools can have 3/4 unemployment while great schos are 3/4 the other way. Many T1 school's around 60%, so 2 out of every 5 are fucked.
Of the remainder, air becomes an issue of A) the quality of the job, and B) the salary relative to the cost/debt.
Without getting technical, of those 3/5 that have jobs, maybe 1 will have shift paying or prestigious job and the other two will have a relatively low paying job that doesn't have good long term prospects. If your debt is minimal, it's ok to be in that group, but if you paid anywhere near sticker, you maybe we pay off your debt.
So, for every 5 students, that's one good outcome, 2 have low paying, but at least real legal jobs, and 2 who are unemployed or flipping burgers (and massively in debt)
