As Obama fails on another campaign promise, this one to end the war in Afghanistan, and as that war moves into its 15th year, it is important to remember the US has spent around $110 billion (no one knows the exact amount due to poor record keeping) to “rebuild” that beleaguered nation, so far.We say “so far” in that the spending continues, and like the end of the war itself, as no foreseeable end date.So how is that rebuilding thingee going?Not well, according to the Stockholm International Peace Research Institute, which issued a report saying “The Afghan private sector has thus far failed to fulfill its potential as an engine of economic growth or an instrument of social inclusion.”In addition to America tossing that $110 billion of taxpayer money into the hole, foreign aid groups have been flushing away $15.7 billion a year. Taken together, all that money now accounts for around 98 percent of the entire Afghan gross domestic product.In something of an understatement, the Stockholm report notes “Popular dissatisfaction with unequal access to economic resources, flawed public services and goods, the adverse security situation, and predatory government activity undermine an effective and sustainable private sector.”Among its other findings, the report blames foreign governments and aid groups for giving Afghans too much money, which they couldn’t spend wisely even if the country weren’t riddled with corruption. Intended to improve government and grow businesses, the report concludes the aid instead merely sustains kleptocrats.As for what the $110 billion of US money could have purchased had it been spent to rebuild America, VICE notes it is enough to dig a new train tunnel under the Hudson River between New Jersey and Manhattan, lay a high-speed rail link from San Diego to Sacramento, reconstruct New Orleans’ levees after a storm like Hurricane Katrina, and still have around $10 billion left over to construct a few hundred schools from Chicago to Houston.Reprinted with permission from WeMeantWell.com
