Actually, rising costs to insurers are by design: it’s to run them out of business so government care will be the only choice left. Liberals just shy away from saying what they really want to do.
It is unlikely the US government has or will have the resources to subsidize alternative forms of insurance ~ which may well end up privatizing the provisioning of all medical care in the US ~ straight up patient to doctor type care.
The consequences will be that the people the Democrats claimed they wanted to help ~ those without insurance, or those with pre-existing conditions ~ will be without any degree of medical care and will be dying in the streets.
Philosophically I don't have a problem with that ~ provided the costs of medical care come down ~ which they will once it's privatized again.
