My wife's a lawyer, and she fucking hates it.
But to answer the OP, I've got an MBA from a top program. I actually really like the job I have as a result, but the the long hours and travel detract from being able to focus on IM work. While the debt is annoying in the short-term, it's good to know I can find a high-paying job in any economy when I need to. Plus the relationships/connections my grad degree afforded me open a lot of doors for freelance consulting work when I decide to leave the rat race. The downside is that I'm not as hungry as a lot of people here, so I'm moving at a slower pace. But the last 9-10 months of pecking away on the weekends is starting to pay off, so I'm getting there.
But that's just the employment/money-making side of things -- purely practical matters. Undergrad was a far more transformative and fuckin' kick-ass five years. Sure, studying East Asian history, pumping myself full of drugs, working pizza delivery, etc does jack shit for the pocketbook now but I'll be damned if I traded the college experience for anything. To each his own, but I'm really glad I didn't spend those years stuck behind a computer. Plenty of time for that now.
