I agree a country in such debt should reduce necessary expenditures - both at home and abroad.
Much better to invest at home - but there must be an asset at the end of the investment.
Unfortunately I cannot see any tangible assets as a result of the 2008 stimulus. No Hover Dam or National Highway System or modern day equivalent.
yeah it would have been nice if that money had gone to infrastructure that is badly needed. also with an increasing population and shifting populations new places have different demands and repair needs.
