"Putting people back to work" in a bunch of government work programs paid for with tax dollars won't help a thing. See, it's a funny thing about government workers: THEY DON'T PAY ANY TAXES. Oh, sure, they get the usual deductions out of their paychecks like everyone else does, but since their ENTIRE paycheck is taxpayer money, they are simply sending a little of it back. Government workers make NO CONTRIBUTIONS whatsoever to the tax coffers, so increasing their numbers without a serious pro-business agenda is economic suicide.
If Barack Obama wants to "put people back to work" and "save the economy" he'll make sure it's private enterprise that thrives by lowering business taxes, limiting costly regulations, keeping energy costs down by drilling for oil while also seeking alternative energy, and keeping the capital gains tax (which represents an investment in private enterprise) as low as it is or lower. If he doesn't do those things, then he either doesn't understand economics or isn't serious about jobs growth and wants a nation of dependent people instead. Government jobs and bloated social welfare programs only last as long as private businesses and their employees continue paying taxes.
