Most consensus is that normal market forces don't work very well for health care for a variety of reasons. Firstly people are notoriously terrible in predicting what coverage they might need (so any choice offered becomes of nebulous utility right off the bat). Secondly, because of the nature of health emergencies, most people are not in a good condition to investigate their options at the time of care. You can spend months researching the optimal smart phone for your budget and use case, you spend the same amount of time on looking into your cancer treatment you'll end up in the same place as Steve Jobs. For the average consumer, demand is very inelastic when it comes to ~not dieing~ and availability of information + expertise to evaluate said information is sparse. Single payer is the far more efficient solution for everyone except the middle men profiting off the current system.
