Medicine is an 8 year investment. Not a hole. No one forces you to go to medical school. Just like people spend 4 years in a ****-dead-end job because it'll give them the experience and connections they need to get ahead.
Look, if you believe you can make more money in another field, go for it. I'd love to see it. The fact remains that medicine is one of the surest bets out there. Even with the high loans today, the return on investment is unparalleled for the vast majority of people. Can you make a superstar app and make 500,000 in one fell swoop? Sure. Is it likely? Nope, not even close. You and 10,000,000 other John Does are trying to do the exact thing and less than .1% will even sniff the ROI that medicine will entail. .1% of those people will be the rockstars that come up in this thread. That's not even an exaggeration by the way.
Secondly, 320k in loans will not balloon to 600k after residency unless you decide to train for 15 years. On a 10 year repayment schedule, you would accumulate ~20k/year in interest. Assuming you make no payments, your total loan burden would be 380k; not 600k. If you want to hit it big in engineering/software/finance, you better brush up on those math skills.
$80,000 over 4 years, assuming unsubsized loans, 6.8% estimate (yes there are 2 percentages...) will be $380,000 out of med school, 0% in loan fees. Rough estimate.

Finaid states: "It is estimated that you will need an annual salary of at least $524,766.00 to be able to afford to repay this loan. This estimate assumes that 10% of your gross monthly income will be devoted to repaying your student loans. This corresponds to a debt-to-income ratio of 0.7. If you use 15% of your gross monthly income to repay the loan, you will need an annual salary of only $349,844.00, but you may experience some financial difficulty.This corresponds to a debt-to-income ratio of 1.1."
Of course you can always pay more or less depending on your salary, whatever your salary ends up being.
