Go with the parents! If you screw up your life and can't pay them back, then it's no biggie, and they still HAVE to love you 🙄. However, if you screw up and owe $$$$$$ to Sallie Mae (or whoever!), it's a different story. Now, I'm not saying that you'll screw up, but if my parents made enough to pay for my medical school, hell yes I would take it! Who in their right mind wouldn't? That's just another thing that you don't have to worry about while in medical school. It may not teach you 'proper values,' but you'll be making enough money after residency that it shouldn't matter a whole heck of a lot. But, as I said before, even if you do screw up, it's no biggie.
