I'm at about 36K after my Masters. I was at nearly 40K after my undergrad but then worked for three years and payed off as much as I could because I hate having debts. Am taking out a student loan again during my Masters (which I have now placed in GICs) since I won't have to repay it for at least 4 years (I'm starting a PhD in the fall) or more. I plan to take student loans during my PhD if possible and also invest them so I have some extra savings when I'm done and have to pay off the huge chunk. I wish I did that with portions of my student loan in undergrad, something I am now helping my brother do. This way, a little bit of interest accrues and you didn't spend ALL the loan money. I came from a poor family so in 1st year when I got all that money even though I was working a good job, I blew it all, because they make it seem like magic money - I had never seen so much money until that point. It's so unfortunate, but much of my cohort did the same.
There's not enough financial education for students in high school and during undergrad that could help alleviate some of these problems. I bet if I was just a tiny bit more clever I wouldn't have had my loans as high as I did. Not to mention in Canada, student loans accrue DAILY once you've graduated. Not sure how it is in the USA.
