we're in this weird limbo where we havent privatized enough of healthcare to see many of the potential benefits yet we don't get any of the benefits of a government run system. you still need a certificate of need to establish new medical facilities, regulatory burdens vastly inflate the costs of medicines and procedures, hospitals are not allowed to turn anyone away which makes insured people cover the costs of uninsured people, insurance companies cant compete over state lines, and there's bloated administrative costs because of the patchwork and needlessly complex billing system.
