Stimulating the economy…

I touched on a version of this issue many posts ago, but it comes to mind again.  I’m wondering if every time the President mentions the word catastrophe, he isn’t also accomplishing more than just motivating politicians to get off the pot.  Is the mere mention of the word ‘catastrophe’ also stimulating people to start buying things to help them survive in case of an economic collapse?  Wouldn’t that, in itself, temporarily stimulate the economy to some degree?  Of course, that kind of buying would not signify confidence…though I suppose it could be misrepresented or misunderstood as such.
