Any other industry would be happy to have the government subsidize their product.
Guaranteed income and profits should look pretty good in times like these.

Their worries about regulation are foolish. The US has never regulated any industry in a way that seriously reduced its profitability, usually quite the opposite.

They forget about the profits to be made from providing health care to those who currently cannot afford it, but would receive it under government subsidy.

Our current system is closing down hospitals all over the country. No health care is being provided by a closed-down hospital, nor are any doctors or nurses being employed there.
The hospitals are not being closed down because we have all suddenly become so healthy that the hospitals are no longer needed. It seems that our system "rations" health care too.
