Here's how it works:
* The profit motive drives people to make more money.
* One inevitable outcome of that is that people innovate new ways of delivering high quality goods/services for less cost, create new industries with new jobs, and invent neat new things that enhance our quality of life. Almost everybody likes this. It works great. It's one reason most more-socialist-leaning governments in Europe still have predominantly market-driven economies in most sectors. Hell, even China has slowly but surely moved to a more market-driven economy. Mao himself tossed socialism out the door on their farming coops when that wasn't working out for them.
* Another inevitable outcome is that many will poison/murder/nuke the environment/your children/our schools/the legal system/our health/our quality of living/real estate/the global economy/the internet/very small dogs/etc... to make a higher percentage if there aren't any rules to prevent them from doing so. See Monsanto, the textbook industry, US children with lead poisoning from Chinese toys sold in the US, and other crap that makes news on a daily basis, etc... Consider that most other western nations have nationalized health care. And yes, there are downsides to that but what doesn't happen is that a minority of the most expensive patients are denied service that their coverage at least appeared to promise because that eats into somebody's margins but they know they can get away with it as long as 98% of their customers never have a problem with their service.
So, when our conservative friends start polishing that old chestnut about the "free" market it's because our new corporate overlords want them to start removing regulations that protect us from that third bullet point again for like the umpteenth time since the first naive fool actually took the words trickle-down economics seriously.
The notion of a free market is a paradox. It cannot exist because it would inevitably destroy itself. It's a game without rules that nobody wins. They know that but they can and will cheat at every opportunity we give them. So knock it off with this free market foolishness. It's naive and it's been making a tool out of libertarian and republican voters for decades now. There's a middle ground between having an excess of rules that hamper market growth unnecessarily and having next to no barriers to abuse whatsoever. That place isn't about being a moderate, it's about "duh." Because nothing else promotes a healthier, more vital capitalist sector than rules that guarantee competitive practices and protect us from abuse.
And when the very nature of a given sector, like health insurance, makes it near-impossible to regulate owing to extreme motivation to abuse given the profits and ease of getting away with it, just say !@#$ it and sprinkle a little socialism on the problem already. Healthy not-dead not-financially-ruined people buy more products and/or start new businesses. Health care is infrastructure. If we can operate health care reasonably at a small loss, it's well worth the investment to do so.
