Healthcare for 300 million people already is at stake for the benefit of the so-called 50 million people who don't have it. This law wasn't written with the intent of making healthcare affordable for EVERYONE.
Everyone already had healthcare, because it is now and has been against the law to refuse to treat someone who shows up at an emergency room. What everyone didn't have, many for perfectly good reasons, is health insurance.
To the left, this may very well have been a problem of the lack of health insurance, but it's never been a crisis of healthcare. The cure, in this case, is worse than the disease.
