I agree with lucas, but more because of the faulty Keynesian economics described in that article.

Innovation and productive activity "generates" money, not consumption.

It doesn't make any sense to say that if I purchase something off of the McDonald's Dollar Menu, I have somehow generated and additional $2.08.

Shaffer's rounds of spending chapter explains it better than the wikipedia article: http://www.rri.wvu.edu/WebBook/Schaffer/chap05.html (not sure why I jumped to wikipedia first).
