> do you think that if there were 10x as many doctors magically hospitals would charge you any less for your stay?

Eventually, yes.

All those unemployed doctors are more likely to settle for working for a cheap hospital and earn 'only' ~$150k than switch careers or stay home on welfare. This would eventually decrease the cost of basic care.

No, for the same reason that I don't think increasing the battery supply will reduce the cost of leather seats. I do, however, think that if there were 10x as many doctors, my checkups would cost less (in both time and money) and my medical procedures would cost less.

I think fundamentally issue is how much expense is okay for healthcare. Current prevailing thought is whatever it takes.

With consolidation of hospitals and other healthcare facilities: less options coupled with desire that even the most expensive healthcare procedures must be available to all irrespective of individual affordability, we are going to have ever increasing healthcare costs.
