National Healthcare - Common Sense

It recently occurred to me that if I were to come down with some terrible injury or illness, I would be totally screwed. I don't have health insurance. And you can't get health insurance once you've been diagnosed. And there is no way I could pay for my health care, especially for a long drawn out illness like cancer or something. This situation must happen to millions of people regularly. How many poor people are there out there who don't have health insurance? And it's easy to break a bone. Who knows when an accident can happen.
As I get older and seem to get sick more often, this has really begun to worry me. What if it turns out I have a really bad disease? It seems like only people with money get help. Or if you happen to be a cute child with e freaky new illness and you can be used to raise money. This is a terrible system. One I know that is trying to be changed as I type this. And I have to admit that I am extremely ignorant when it comes to the ins and outs of the argument over national health care. But from that ignorant standpoint, based solely on common sense, doesn't it make sense that everyone should have access to adequate health care? At least the basic emergency and preventative care? When I lived in Vermont we had a state health insurance system. If you made under a certain amount, insurance was free, after that you paid a deductible based on income. I thought it was great. It was better than private insurance. I got rehab bills taken care of, they paid for my methadone medication across state lines, and it was affordable. If it meant my taxes were a little higher, they weren't high enough to be noticeable. But the benefits were noticeable. How can people not want to pitch in to help everyone around them be healthier? Don't they realize we are all connected?
