"Killing the Recovery" - NYTimes.com

I still don't understand why spending by everyone is not important. Is government the only entity that should spend more? Should everyone else only save or spend just what's necessary? I don't see how a yes to that question advances any economic ball very much. What are the workers expected to do who might be hired by government anywhere - spend the money they earn or save it? Why does no one address this? I fear it is because there is no good answer.
