I assume the phrase "no amount of safety is enough" when it comes to health care is a false statement, it's an economic problem: Am I/is the population willing to pay 1000% (10x) more for say, 2% to 1% (2x) improvement chance in the person fucking up my teeth?
With that in mind, I wonder is going to school for a long time necessary? I think we have a return-on-investment curve (or time in school vs chance that the person fucks up) that plateaus at some point here. Maybe it plateaus where the Indian requirement is, and people in the US stay in school too long for very little returns.
