As to the OP's link, I was reading The Complete Tightwad Gazette, and Amy had an article entitled, "Is Frugality Bad for the Economy?" She makes a pretty solid case for our economy needing more savings and less "spendings."
In summary, she cites Paul Tsongas' argument that businesses require venture capital, which is "good debt" required for economic surplus. We lack venture capital because we overspend, which gets us in to debt, which requires a bail-out, which raises taxes and, very often, gets the government into debt.
What's also fueling this vicious cycle is the "outsourcing" of American jobs, a trend that that culminated with NAFTA and GATT and is continuing in countless other industrial sectors. The and short-sighted claim that we need to "spend our way" to prosperity, even if it means consumerism-by-credit, glosses over this fact.
During WWII, it was your patriotic duty to save and ration the nation's resources. Contrast that with today, when we "keep America rolling" by purchasing a gas guzzler. We've come a long way, baby.

It may require some gradual weaning, but as a nation, we need to stop relying on consumption to fuel our economy. Our current mentality in the long haul won't help the shopping mall pretzel stand employee--just the CEO of the pretzel stand franchise.
Forgive the meandering musings. If any good comes out of this Recession, it will be Americans rethinking their priorities.
