One of the things that Republicans proposed was that private insurance be sold to individuals across state lines. Basically, you get a health insurance policy for yourself and no matter where you work or where you live, you can keep that policy. The Democrats rejected that.
The whole ideas that you get health insurance as a benefit tied to your current job comes from the Democrats (FDR). It's a bad idea for precisely the problem you mention. Lose your job, lose your insurance. If you get sick while looking for another job, your next employer may decide not to provide health insurance for you -- you're already sick, so it would be a foolish business decision.
It's a real problem. The Republicans have the solution. The Democrats block the solution and perpetuate the problem.
Thank you for your serious and polite response. Now, what is this about state lines?? Aetna is one company that is country wide....how is this state limited?
