Let's try a real world test. If rising sea levels are inevitable and all the ice will melt, lets get the federal government out of the flood insurance business now. Let the people who want to live in harms way pay private insurance prices (if they can find it) or have the resources to rebuild on their own
How many votes do you think you could get for that in congress?
Oh, Oh, Oh, I know, I know, not enough...
Why? Because so many of them own property in the flood zone...
