Biden's Medicare Proposal

Joe Biden has come out with what seems to be a compromise on the Democrats "Medicare for All" chant as he's proposing that it be expanded to allow it to accept people 60 and older. I have two basic objections to this proposal:
1. Medicare does not pay doctors or hospitals nearly as well as private insurance does. Any expansion of Medicare is going to yield less income per patient for doctors and hospitals. The result will be more hospitals going out of business, mostly those in rural areas that are already stresses. Doctors being forced to see more patients per day and spend less time with each patient. With a larger case load for doctors to juggle, the result is almost certainly to be a reduced standard of care. They are going to have to infuse Medicare with more money to offset this effect, either through higher taxation or higher premiums for those already on Medicare.
2. Allowing 60+ individuals to go on Medicare will result in more people to retire early. Although I feel a bit hypocritical for bringing this up as I retired at age 63, nearly 3 years ahead of my full retirement date of 65 years and 10 months, but it's going to encourage more people to start drawing on Social Security ahead of their full retirement date, one of the things that many observers say is hurting the system. The push has been to try to give people an incentive to work longer. This proposal is counter to that line of thinking.
