No, competition is often good and bad. Buyer beware is fine with widgets and other market services, but we have good experience with snake oil salespeople in this country. Health is important, we agree, but don't fool yourself that competition fixes all evil. Long a ago, so hard to link, but there was an article on healthcare titled "The Revolution." Late seventies or early eighties. They noted at the time that no matter how many doctors you brought into the area, the market didn't saturate. Instead, they ordered more test, brought in more and more people. You might recall how doctors owned X-ray machines and such, which promoted red ring more and more tests.
The point is, the market was working, competition was high, and costs were sky rocketing. And even then, the costs for those not paying we're being passed along to those who do.
