I can't understand why people are incapable of simple math.

When someone goes to a doctor and runs up a bill and doesn't pay. Here is what happens. The Doctor "expenses this out" "writes it off as a loss" thereby offsetting his or her tax liability. That will omit that much tax owed on other income. The Government operates on tax money received. If they don't get it one place, they get it somewhere else. So you can plainly see, we are already paying for "Government funded" healthcare and not getting it. Think about it. No free lunches, costs are constant.
