Within our healthcare system, a truly competitive marketplace could compete on:
-hours available for routine visits
I imagine most people would be willing to pay more if they could get routine doctors' visits from say 6pm - 10pm weeknights and maybe 7am to 5pm on weekends.
-offering a variety of plans that either emphasized or de-emphasized prevention
Imagine if we could pay less for healthcare if we committed to follow doctors' orders concerning eating habits, exercise, and other lifestyle changes.
We need the government to guarantee access but not to control the actual delivery of healthcare.
A properly designed system can have competition between providers, and allow consumers purchasing power.
At some level we either have to change our choices as Americans or ration care.
I prefer to expand our options and make better decisions voluntarily.
