There was an article posted on HN recently about the asymmetry in cost of providing an ambulance service vs the cost of the per-ride service. The cost of a medical degree, and the training on top of the degrees, may seem waaay too high but I am sure that when you need the service you want it to be there. I think if I break a leg, need an emergency surgery, etc I will be okay with $0.00001 of my taxes going into the pile needed for paying off those $500k loans.
