@A Lone Voice,
It won't work anywhere, Lone Voice. Look at where it has been tried. I think Japan has tried it, and it isn't working. The Great Depression, or FDR, is Obama's model, but there is not proof it worked then, in fact 37-38 were some of the worst years of the Depression, and it was the war that brought us out of it, alot due to selling materials the couple of years before we actually entered the war.
Here is my analogy. Public Works, or government spending is like dipping into a spring fed lake with a bucket and pouring it out back into the lake or around the edge of the lake. Real economic growth requires the spring to be flowing to replenish the lake, to feed the lake, to raise the level of the lake. But if the spring is slowing down or stopping, simply dipping into the lake with no influx of new water, it gets staler and staler. You might be able to dampen the shores where it has dried up, somewhat, but doing so only increases evaporation, and the lake level drops even faster.
