This was a pretty good, animated explanation [CLICK HERE.] It points out the similarity of Obamacare to mandatory auto insurance ('cept that poor people still have to pay auto insurance.)
Which is why I purchased my 50 cc scooter -- to avoid paying all the money, from auto insurance to an operator's permit -- only to have the Massachusetts law change two years later. Now I am required to pay for: liability insurance, operator's permit, town fees for a "vehicle," annual registration fees, and inspection fees. Had I known when I purchased my scooter, I would have purchased one that can go fast enough to travel on the highways.
So I understand why people are agitated at the thought of more mandatory fees. However, I think could accept mandatory health care coverage better than I accept having to pay fees so that I can drive a 50cc one seater scooter around my hometown of Arlington, MA. But someone's gotta pay for our highways, right?
