2015 Milliman Medical Index - Milliman Insight
PPO is the most expensive form of insurance you can buy.
HMO is maybe 60% of the cost with a high deductible.
Still the cost is a lot but most of it is paid by employers and passed along in the prices of the goods you buy. The alternative would be additional taxation and governmental price control or manipulation.
Healthcare everywhere is just a cluster fuck robbing peter to pay paul -- no one works for free (intentionally, notwithstanding volunteer workers).
