A lot of disease is a result of obesity. The only way Medicare could pay for prevention is to wire patients mouth shut. That would work.
You’re right!
And its really the only way that universal healthcare could even have a ghost of a chance of working. The government control your intake and your activities. (Actually it would only slow down its rising costs & bankruptcy since all are bodies will get old slow down its responses to disease, etc. and we will die. It can’t be turned into a zero sum game! So universal healthcare will never work!)
