You’re referring to internal travel restrictions -
how about not allowing flights into the country from places with ebola?
Same thing.
The major companies in the US would scream. So would the smaller ones for that matter.
I remember some one (wish I had saved it) saying that after 911, you would never see an intentional stoppage of airline traffic again. It was simply to costly to the airlines, major businesses, and the public mood.
Sadly that is how decisions are made. Having a few thousand die of Ebola will be rationalized by “Well, at least we let the Cowboy’s season continue! Look at how many jobs we saved!”
