1944 poll: Would you rather have Social Security handle health insurance?

[Progressive dog]

17. Medicare covers about 1/6 of the population

and when started, there were fewer people over 65. As far as people on Medicare, it's pretty much the same as any health insurance, with you paying monthly for part B if you choose to have more than "in hospital" coverage, finding a way to pay the 20% of part B costs and you buying a separate drug plan with co-pays, a doughnut hole, and perhaps a deductible. Of course the drug plan will have a formulary and won't pay for all FDA approved drugs. You have to re-up to drugs and/or advantage plans each year. Most change formularies and patient costs each year.
Then there are dental costs (you have to buy coverage), vision (you have to buy coverage), long term care where you go broke first-then you might get medicaid.
This is at a time when you usually need more healthcare, when your income has decreased, when it is certain that you are not as physically and maybe mentally as capable as you were. That's what you claim is relatively simple.
BTW I am one of those people on medicare and I paid into the system for over 40 years (and my employers matched those payments) so that I would have some affordable health coverage when I retired.
