In reality I think many healthcare entrepreneurs either get caught in the existing framework (and dependent on it), or find the regulatory and other hurdles too hard here.
That said, I still think there is a LOT of room to improve cost efficiency here, and the right entrepreneur could do it. It's been done in other stagnant segments of the economy... I would like to see an Elon Musk-type entrepreneur open efficient hospitals here like this guy is doing in India.
