No we don’t. We have a shortage of doctors. Increase availability of medical education, lower doctors’ wages (higher supply pushes prices down) to approximate developed-world standards, and there will be no need for rationing. People who clamor for rationing don’t know how fucked up the pricing structure (including that for procedures) is in the US.
We already use LESS services than other developed countries, yet we pay more. Fix the system before introducing tech-weenie Band-Aid solutions that limit personal interaction even more.
