I love our Canadian health system. It isnt perfect though. My only complaint would be the 3 to 4 hour wait to get in to see a doctor in an emergency ward depending on the severity of the person. BUT, I have no problem keeping that wait time versus pay out of pocket health care.
Also, the Canadian system may very well not work in the USA on a large scale. It might work well with Canada having only 35 million people versus the 37 million in California alone or 315 million in the whole USA. That difference being so astronomical, it would be very tough for the USA to assemble a new system especially when cloning another system. Risky
