Fear mongering? Obama? Dude, Obama doesn't do any fear mongering, he just tells it like it is, then presents solutions to the problem in an optimistic style. If you want fear mongering, look no farther than the last 8 years, when we were constantly being told that only Bush could keep us safe; now that is fear mongering.
As far as the stimulus goes, it gives us some money, sure, but its main point is to spend money in various ways. The businesses hired to do government jobs will then be able to use that money to hire new employees, thus creating jobs. This worked before in FDR's New Deal, and with any luck, the bill will be big enough to do the same 75 years later.
