I also keep wondering, is Medicare For all" the Medicare I am now on? The one where medigap is not exactly cheap.
Cheaper than not having insurance at all and still, even in a lot of single payer countries, there's sometimes some kind of gap policy happening, plus there's almost always an elite Cadillac plan for those who want to fork over and jump in front of the line to the private sector.
Doctors and hospitals in those countries seem to do well enough but if we're talking about the well being of the patients, seems they do much better than we do.
It's obvious we will likely wind up with some kind of tiered hybrid and not exactly pure M4A, no matter how badly Sanders wants it.
