A mandate to purchase health insurance that isn't enforced isn't worth the paper it's printed on.
A mandate to purchase health insurance that is enforced, for example by garnishing wages, is a political disaster.
So can we stop talking about mandates and start talking about making health coverage affordable and available to anyone who wants it? That's the difference between Democrats and Republicans on health care, and it's a winning difference.
I have no problem with companies making a reasonable profit by providing a necessary service, but the service must be provided before any profit can accrue. If they can provide the same level of care that the rest of the developed world enjoys for an equivalent percentage of GDP or less, fine. If not the government needs to step in either as a regulator or as direct competition or both. The insurance companies, being publicly licensed, do not have an inherent right to exist they have the privilege to conduct business in a prescribed manner at the pleasure of the government, i.e. we, the people, last time I checked.
If you're interested in change then I hope to see you in 2012.
