KISS look at Massachusetts.
The model for what is proposed. How far in the red is that state??? Hello?
That is an unrealistic comparison willow tree.
First study after study has been done showing that universal health care if implemented throughout the country will actually drive health care costs down.
Secondly if individual states try to go it alone they are at distinct disadvantages . The first thing the insurance companies do is raise rates and say tough luck if you don't like it we will just pull out of your state.
For instance Kentucky tried several years ago to put caps on medical and auto insurance rates. Insurance companies just pulled out of the state. Took their ball and went home and said we won't play unless you let us charge what we want.
States like Massachusetts that try to go it alone are seeing the insurance companies raise rates sky high because they are being told they cannot exclude people for pre existing conditions. With insurance rates that high, hospitals and doctors naturally want their share of the pie so rates go up across the board including for the state run programs.
Common sense says prices cannot be controlled unless all states are in and coverage is universal across the nation.
Naturally the insurance companies don't like that because that means they will have to compete for a share of the pie. It means they won't make multi billions a year , they may just make a few billion.
