Experts have been wrong about a lot of things in the past. In this case I'm not saying "everyone is an idiot and missing the obvious", I'm saying "politicians and economists are idiots and are missing the obvious", because this is a case where the average non-academic person would intuitively believe outsourcing would be bad for American industry in the long run. I'm not saying that more research shouldn't be done into this, but if it's correct than the incorrect conclusions of economists helped to decimate the American manufacturing industry. If this is the case then how did things go so wrong, and how do we avoid something like this in the future?
