There is another good reason to create a national health care plan: so that American's freedom of movement is not inhibited. Many private health plans only cover medical providers in the insured's local area. As a result, if an insured takes a vacation and gets sick or hurt while away from home, many times their illness or injury will either be reduced or not covered by their health plan at all.
This policy is irrational. Americans should be free to explore and see new things. They should not have to worry about a reduction or denial of health benefits while they are away.
