it still does not solve the problem
premiums of any kind are a result of the cost of payouts .... thus if the cost drivers are not held in check it would not matter if it is medicare or private insurance i.e. the premiums still go up
the government addresses the problem by lowering payouts which may, in itself, be a cause of rising doctors costs
the challenge is to find an economic solution which manages rising costs at an acceptable level .... ACA attempts to do that, but like an octopus trying to walk on land, it gets in its own way
while medicare increases the pool size, which should have a reduction in premiums as a short term effect, it still will not inherently reduce cost drivers, which in the long term continue to cause premiums to rise at the same rates
