I have a feeling that the health care debate has it's pros and cons, but if there is any reason everyone should have health care I would explain it like this: If you ever go to the ER or get an ambulance ride, the costs are fairly high even with health insurance. The reason why it's higher than you would imagine it should be (like hundreds of dollars for two vicodin at the ER) is because it's hospital policy that ERs & doctors cannot refuse anyone who comes in with a life threatening injury (say from a random car accident) or someone who is homeless and sick. If someone comes in with a injury without health insurance, the hospital treats, bills & likely doesn't completely collect because the cost is astronomically high for those without insurance. Additionally, if the person who came in is homeless, I would imagine the hospitals have some sort of loss of resources write off policy due to homelessness. Now, the homeless problem will never go away, but the cost of individual visit to the ER would be decreased if everyone had insurance (kinda like car insurance), because the insurance companies would be more likely to pay off more of the cost (hopefully decreasing loss per individual).

There is no reason why any one person has to have health care insurance, other than make it illegal, like driving without car insurance. Counter-intuitively, society is built on taxes and government mandated insurance enables the rest of us to pay for something that we don't individually want, but we all benefit from.

Here's a strange tangential video that comes back 'round to this main point.
