Ann has learned from her mistake. So should you.
One purpose of the states as "laboratories of democracy" is to allow different systems to operate without committing the entire nation to such schemes. If the MassCare system turns out to be awful, then Massachusetts can scratch it, and your elected reps in New York can have the evidence to avoid adopting it in the Empire State.
Right now, we have a system where the federal government mandates that hospitals must give emergency room care to those who can't or won't pay for it. This in effect amounts to a system of "free" health insurance, driving up the cost of insurance for the rest of us who pay for our coverage.
