I think that they understand. They're just participating in the psychological game of "getting people to spend money". In other words, their goal was to make the people think that everything is OK and it's acceptable to carry on as usual. Kind of like our government telling everybody to go out and spend post-9/11.
After 9/11 we were in a normal biz cycle (for a nation that had it’s economic center hit by terrorism)...things bounced back. After 11/4/08, all things changed - nothing is the same.
