Capitalism is great at providing a service when it's profitable for someone to provide it. But what if, for one reason or another, no market exists in which it can make someone money?
Take, for example, medical research. I have told any overseer of my education that I have no interest in any type of research, yet I still got the pleasure of mandated attendance at several lectures on how a drug goes from basic research to the patient's medicine cabinet. The system is set up to make it easy to make money getting new therapies to market. Companies with the ability to make huge sums from a patented medication can fund huge amounts of research to back up their claims.
These claims made in research go largely unopposed, except the rare bit of backbone from an underfunded, partly industry-funded FDA, which has an annual budget of about $2 billion in regulating industries with a $1 trillion in annual sales. Who else would have a motivation to fund research to keep a new drug off the market? Competing drug companies might have an interest, but would they really want to provoke responses which would lead to a system where they have to fight harder to get a product to market? Individual insurance companies or consumer groups would run into the Free Rider problem, with insurers and consumers who don't want to pay for opposing research would benefit from the lower costs despite their lack of contribution. So you wind up with a system with unopposed research on new ways to spend money. Is it any wonder that medical costs are spiraling out of control?
What is needed is more research on ways to limit costs, and because of the market's failure to provide it, it must come from the government. It might lead to a dystopian hellscape of death panels, so it would be helpful if there were already a system in place which would freak the fuck out if any government body ever said "we can save $x million for every patient we allow to die" to keep the system from ever preferring cheaper treatments which led to worse outcomes. We can use the paranoia of Fox News and the Drudge Report for a good purpose.
The program I'm discussing, of a government body seeking ways to limit costs without affecting outcomes, is essentially the role of the Independent Payment Advisory Board, a fifteen-member body set up under Obamacare.
