Generally speaking I agree with you. I said costs would change, you just assumed I meant downward. However, I admit I don't know the full impact because the fact is that right now many people are getting care and not paying their bills and you are paying for them. Right now you pay through higher costs passed on by the hospitals, with a government plan you pay through taxes. I don't really know which way is worse.
There will always be bankruptcy for medical payments of course. The question is what is a reasonable level? If 99% of the population was going bankrupt for this reason, it would seem something is wrong that needs to be addressed. Of course percentages are no where near 99% but you get my point hopefully. What is an acceptable rate?
That would be great but we don't live in that world so unless you are happy with people not paying their medical bills at the rate they are now, and jacking hospital costs up, just telling someone to be more responsible won't solve the problem.
Once again, this would be ideal but teaching an entire nation of people (many recent immigrants) to share your morals is going to be difficult and take a lot of time.
