article's conclusions are smart:
"A better agenda would attack the causes of unjustifiably high prices. That means blocking hospital mergers and contracts that hinder competition, and fewer rules that protect existing providers from new rivals. It also means giving patients and employers real choices: transparent pricing and insurance designs that reward consumers who discover more affordable care. When patients who choose lower-priced care can share in the savings, they put pressure on prices in a way no bureaucracy policing thousands of services can match.
Price caps do not curb the costs of delivering care. They merely shift those costs to places that are harder to see. The answer is not price by decree. It is institutions that help patients, providers and payers discover better prices and better care."
