Be careful not to assume that implementation is much simpler than it actually is. Oversimplification is a political problem for both right and left when it comes to health care.

Also, definitely avoid conspiracy theory thinking that Democrats wound up with ACA rather than "single payer" out of corruption and malice, rather than realistic political consideration. That's another pathology. I don't believe there are any Democratic politicians who want health care to be more expensive and difficult! They want cheap, universal, quality, and fair. Duh.
