Most people who support some kind of single payer, medicare for all or increased government involvement obviously never have experienced it.  Try going to the VA for good care.  It would be a great model for what health care in this country would look like.  Health care in most other countries with single payer work bc we subsidize it via lower drug and especially technology prices.  If that subsidization ceases, good luck to the UK, Canada, France, Germany, and Japan.  

I also think once people in this country experience true single payer, we would see a revolt like we haven't seen since the 1930s.  My personal opinion.
