Personally, I would  always choose to trust professional administrators, who I had an opportunity to vote for, to run our health care program than a for-profit private sector organization. Turning health care over to unregulated corporate crooks and greedy insurance firms is  a recipe for corruption and excessive red tape as proven by our current  situation.
Read the book " The House of Hope and Fear " about Harborview Hospital for a realistic look at the health care industry.
