True, but it's even more nuanced than that.
Right now, the government gives tax incentives for an employee to get health insurance from their employer. So if my regular income is taxed at, say, 25%, I could either receive $10,000 worth of health care benefits from my employer tax free, or cash, which would mean I would only receive $7,500. So I'd be a fool to not get my health insurance through my employer. So the employee has a government created incentive to favor getting insurance over money. And the more medical prices rise, the "better" it is for me to choose to get the health insurance.
With a huge amount of people incentivized to get this health insurance, and use it as the way to pay for every single medical treatment they receive, and not just insurance against catastrophic accidents (a certain amount of coverage will be mandated under the Affordable Care Act) the more people completely disregard the cost of the care they receive. Do you ever see a list of services and prices posted at a hospital? They're not paying for it, so what do they care what anything costs? If they don't pay (beyond maybe a deductible) why is it worth it for them to price shop? Insurance companies can attempt to do this to a degree by restricting where people can get care or choose not to cover certain things. But these choices are being legislated away as well, and force insurance companies to cover certain things free of charge, hugely distorting the market even more.
Imagine if we bought food like we bought health care. Instead of getting cash, we'd have a government incentive to instead receive an all-you-can-eat grocery card from our employers. We'd walk into a grocery store, and there would be no prices posted, because the shoppers wouldn't care because they aren't paying anyway. Naturally prices would skyrocket as consumers no longer consider price. The government then would come in, point out the skyrocketing price of food, declare a "food crisis," and take over the whole industry. Having caused the problems in the first place.
Look at areas of medical treatment in which the government is not involved. Sadly there are very few of those, but take for example Lasik surgery. Prices for that drop every single year. Why? Because of natural market pressures. People usually pay for that out of pocket, so they naturally price- and quality shop. Lasik establishments are incented to reduce costs and improve quality. And they do.
The problem is not that it's "for profit." The computer industry is hugely profit-driven, and advances in manufacturing and assembly efficiencies drive down costs a huge amount. McDonald's prices don't skyrocket because they're for-profit. The reason problems get solved and consumers get what they want is because people can make profits providing what they want at a price they want, without government intervention. But parent is right. The problem isn't "greedy capitalism." The problem is that we have gotten so far from real capitalism, though we still think that's what we've got, and whenever something like this happens, someone points out capitalism and greed as the problem and insert even more damaging bureaucracy.
