You’re right. Every time an administration, republican or democrat, passed regulation on healthcare our policies were negatively affected. As a avid shopper for health insurance over the years. I watched the dominoes fall one by one.
However, there was no larger more significant challenge at one time to our healthcare than the one Obama passed. (In recent history)
Over the past couple of years I know of at least 5 good doctors in different fields that stopped practicing, stopped taking insurance or closed their practice to new patients because of the obamacare environment.
(A famous pediatrician whose medical malpractice insurance wasn’t covered by patients insurance payments. That pediatrician now takes cash only. A high risk OB who now takes cash only because insurance companies would send payments of $800 for full term deliveries. A vey well liked internist who closed his practice to new patients because of compensation.)
