I fully comprehend all that....I’ve a million published words plus on Obama Care and health care - and hundreds of interviews on the subject. What you are not aware of is how many doctors and others are WAAAY ahead of you on this, and provisions have been made that you are not aware of.
There are hospitals, with state of the art doctors and procedures and equipment in many states already set up - taking only what we would call concierge type patients. Gone are the massive wings for fund raising and insruance and government paperwork and for indigent care.....just flat out state of the art surgical centers. They have taken the space shuttles and made them smaller, leaner, more efficient but just as magnificent, or moreso, with regards to care.
And your point that the concierge model would not work for hospital care is just not the case. This industry is already well under way.....and it sounds like you are not aware of it.
Of course, the best and most perfect hospitals are in Tel Aviv.
