"Medicare for everyone" has a nice ring to it and everyone understands it.  But there certainly are better versions.  So if we're going to do it, do it right.  Scour the world for the best systems.  Then steal the best pieces from the best systems.  If we're going to build a new system, make it the best in the world.  Obamacare certainly isn't.  Nor is anything the GOP will produce.
