How can a President make people spend their money to boost the sluggish economy?

I don't think that a he or she (she- if in the future) can do that. People are holding on to their money like tomorrow is the last day of life even though many goods in the market have come down in price greatly. And ya know if there's less money being spent, there's more of a bad economy. Last Christmas saw a jump in sales, but I predict this Christmas coming won't be like that. I do understand people cutting back on things, especially things that they don't really need. But I don't know what makes people think that Obama can make them spend to boost the economy. Incentives are good, but if they're not even taking advantage of those incentives, ... what's the use? And I'm talking about people who HAVE a job right now. You have to make things really clear for some folks!
