This is amazing. I graduated from medical school two years ago with $300,000 in debt. I'm a software developer on the side and would love to stop residency to try a healthcare startup and/or pursue a research, but the risk is too great - I need the attending salary to pay off the debt.
One related challenge of inexpensive education is the 'brain drain'. I am Canadian and hold a PhD in Engineering. Tuition was about 3,000 CAD a year throughout my education, with scholarships I ended up no dept at all. Now the temptation is move to the US or Europe is pretty strong, but I am still far from having 'repaid' the gouvernement's 100s of thousands of dollar (with ~160,000$ of in-pocket scholarships) investment in me.
I think free or near-free education is great, but it's a bit of a gamble.
