The costs of medical school make this an impossible ask. The only people that can go to medical school are the people that have rich parents, or are OK with leveraging their future for the chance at becoming a successful doctor. Things go wrong in peoples lives all the time, school gets interrupted all the time. Asking people who just want to help others to pay $300k for the privilege of attempting to get to that point is literally insane. We also have a huge shortage of doctors. Go figure.
