The core issue though is price of medical services.
When an ER visit to sew together 5 inches of a cut skin at 10AM can generate a claim for $40000, something is really broken.
The single-payer can outright refuse to pay $40000 for such a thing while you and I would have that debt hound us for the rest of our lives.
One solution that addresses the root issue is to clamp down on what is reasonable to charge to sew together 5 inches of a cut skin at 10AM.
That is called an all-payer rate set system.
It does not matter who pays - what matters is what price something is available at.
Doctor's regular, scheduled visit? $150.
You pay in cash? ? $150.
You pay in chickens with white feathers ? $150.
Your employer provides you with coverage and they cover the first $500 worth of expenses? $150.
Your'e an uber driver and that doctor would appreciate a ride back and forth for the next month? $150.
When the same doctor's visit can range in price from $10 - $1000 depending on what crap your employer signed you up for, we have a terrible access issue.
The U.S. has one of the best health care in the world, but also one of the higest financial distress including outright bankruptcy for medical bills.
Something's going to give soon as the system starts to come under strain due to SARS-COV2 and it's not likely to be pretty.
