>> The average Canadian taxpayer pays about $20,000 / year for health care costs.
> Your numbers are off by almost a factor of 4, actually. The per capita costs for healthcare in 2015 was $5292
$6000 on the government spending PERSON (plus $500 out of pocket). You probably have either kids or parents who are paying very little tax, if any. Guess who is paying the $6,000 each that they cost? It ends up roughly $20,000 per payer, per person employed full time. That is, each person currently paying pays an average of $20,000.
> that in USD, I would have an annual take home pay of $132 extra living in Texas
Employers provide health coverage in the US. It's not part of take-home pay in either place. In both places, the bulk of the cost is not seen by the consumer (which screws things up), with some incidentals like non-prescription medicine paid for from take-home.
The systems are actually quite similar, just basically in Canada the government runs the one and only insurance company. The only major difference is that in the US you have more choices you make, there are different plans to choose from. Here's something that would be really different:
My wife and I were referred for MRI scans. Since the cost wasn't paid out-of-pocket, we didn't care too much what it cost, but I did ask, for reasons that are slightly off-topic here. The place the doctors referred us to charged $2,000 apiece. I took 5 seconds to do a Google search for "MRI Dallas" and cAalled the first place listed. They said $1,200, but only $1,000 during off hours, and $650 if I filed the insurance form rather than having them handle it (which means they get paid immediately from my HSA). From $2,000 with the "normal" method that 99% of people do to $1,200 just by making one quick phone call! Another $200 saved if I came in after work, when they less busy. That's fully half the cost saved. What if there were a system that encouraged people to cut the costs in half by making a phone call and scheduling the appointment for 5:30, when they get off work.
