He suggested it in his campaign early.He is a businessman. He is a developer, of course which makes some things different but businesses would prefer single payer because it takes the expense of employee medical care off their shoulders.
Better for that one aspect would be for the tax benefits to employee "insurance" be removed and the o-care mandate for employer paid insurance to go away. That thing goes back to FDR and wage/price controls. During the war with controls on employers were not allowed to compete for scarce workers with higher pay. FDR did allow them to provide medical insurance partially tax free i.e. employees did not have to treat it as income. The big companies that were overflowing with war contracts competed for skills with medical insurance. That system was not terminated when controls came off in Eisenhower's first years.
No he did not. I researched it extensively, early in this campaign cycle since it would have been a deal breaker for me.
What he said years before this campaign is that single payer had worked in Scotland because it is a sparsely populated country with very few medical infrastructure or demand to encourage private investment. He said there might have been a time that single payer would have been a solution in America but that was many years ago when America was less developed.
That was an opinion of a man who was a private citizen and many years ago. Since then he has become much more sophisticated about healthcare delivery and costs but even then he believed single payer was wrong for America.
