Frugality adds to economic woes during downturns

Families turning frugal during economic downturns is what's least wanted, though its the most natural thing for families, to do. Thriftiness, embraced by families across the U.S., is also a major reason the downturn may not soon end. Americans, fresh off a decades long buying spree, are finally saving more and spending less -- just as the economy needs their dollars the most.

Usually, frugality is good for individuals and for the economy. Savings serve as a reservoir of capital that can be used to finance investment, which helps raise a nation's standard of living. But in a recession, increased saving -- or its flip side, decreased spending -- can exacerbate the economy's woes. It's what economists call the "paradox of thrift."
