The Myth Of The Thrifty Rich
But there are at least three problems with this plab. First of all, what if due to Republican and Blue Dog Democrat opposition, the handouts to others aren't politically possible? Wouldn't it then given the alleged dangers of austerity be a second best solution to make a deal with the Republicans and extend the tax cuts to prevent the austerity chock from higher taxes next year?
Secondly, even people who save spends as their savings are invested and helps increase either domestic investments (if invested domestically) or net exports (if invested abroad).
Thirdly, as this New York Times article makes clear, it is actually a myth that people with high income are more thrifty than others:
"the Top 5 percent in income earners — those households earning $210,000 or more — account for about one-third of consumer outlays, including spending on goods and services, interest payments on consumer debt and cash gifts, according to an analysis of Federal Reserve data by Moody’s Analytics....
....By spring of last year, the savings rate — which represents the percentage of after-tax income not spent — of the top 5 percent of income earners had turned negative, according to the analysis by Moody’s Analytics. That meant the group was spending more than it made.
Less well-off consumers remained more frugal, most likely constrained by unemployment, declines in home values and the disappearance of easy credit."
It should thus be clear that even from a Keynesian perspective, extending the tax cuts makes sense.
