The answer to that would be clinics with cost based on ability to pay. The care would be adequate, and it would cut down on a lot of over-treatment of subsidized patients.
Lawyers.
Look, I was trained at a NYC municipal hospital that worked EXACTLY like what you are describing.
I had people's lives in my hands when I was 24 years old and working out of a book.
And, I was adequate. Maybe even a little more.
But when you put that care in front of a jury today, you are talking seven figures.
Far too practical a solution (though that was once widely in place and still is in many areas)! It would be deemed to damage the "Self Esteem" of those using the system, as usual, screw the people who pay taxes to support the sinking ship!
