"We've seen over the years that increased government spending does not necessarily translate into an economic boost. If government was the answer, we'd be in wonderful shape," Schatz said. "The government does not create jobs. Businesses create jobs. And taking money from one sector of the economy and funnelling it through Washington to whatever projects they decide to spend money on will not really have a great impact."
Most of the projects from the mayors probably won't become reality but, Schatz said, "The existence of the mayor's list does give people an idea of what they probably will eventually spend the money on."
