Why is preventative health care such a bad thing?

Before this new health care bill passed in the United States, I would hear in a derogatory and nasty tone that the US’s health care system was “don’t get sick.” While I do think the government should have a hand in treating the people who do get sick or hurt, I don’t think that preventative health care is a bad thing. Overall, it makes more sense for people to maintain their good health or to become healthy in the first place than it does for people to do nothing and then get sick and/or hurt.

After all, an ounce of prevention is worth a pound of cure.
