spite of what Krugman and other economists say, Government cannot
really "create" any jobs per se. It can raise taxes and shift private
sector jobs creation to government jobs (typically a malinvestment),
and it can bring production and consumption forward for those jobs that
are genuinely needed (filling potholes and repairing bridges), but once
the potholes are filled and the bridges repaired, one has to ask the
question, "What will we do for an encore?"
There is no free
lunch. It is impossible to spend one's way out of a hole. It cannot be
done and should not be tried. Japan proved it. So did FDR. Ultimately
it was World War II and the destruction of much of the world's
productive capacity that ended the great depression. The US was
relatively untouched by the war, and could lead a worldwide recovery.
That said, there is a genuine need to repair infrastructure and that need must be done at the cheapest possible price.
