But calling the US health care a "market failure" is dumb, because it misses what game the Medical-Industrial Complex and Big Pharma are playing -- what they actually do and want to maximize.
Hospitals (even nominally "nonprofit" hospitals), labs, and especially drug companies are highly successful in what they do that they care about, which is the money markets. It's absurd to say US health care is a market failure when they provide a globally vastly inferior product while still commanding the highest prices by a long shot. If that's failure, it's the kind of failure every other business would like to have.
They are screaming successes at making money, and any "health" benefit is incidental to them - indeed, health hurts their business model, which is why they prioritize new, patentable products and treatments rather than prevention and changing the ways we live (and expose ourselves to pollutants) to enjoy greater health. They have erected enough barriers to competition and built such expensive entry tolls for health care practitioners that very few can refuse to become indentured servants to the "health care" industry or question its practices.
The "health care" system is the single biggest consumer ripoff in America today.
But it's definitely not a "market failure" -- it's just the screaming success that kills.
