Boosting consumer demand through spending in the Keynesian style does not increase GDP, it does not make the economy more productive. If you take a little from the taxpayers and then give it back, you haven't done anything. If you take money from private investors and reinvest it in consumers, you've just reallocated money. If you borrow from foreign countries, you can increase GDP at the expense of future debt. I liked the way the video put it: it would be like taking your retirement fund and using it to go to vegas. Instant gratification, long term problems.
If congress really wants to stimulate economic growth, you need to find a way to increase wage, profit, and other income. You can do that with lower taxes, lower government spending, free trade, and deregulation.
