(In the comments at the link)Same old usual suspects complaining about jobs going over seas; seventy five percent of which would not work in a factory anyway. It sure is a shame there’s not enough manufacturing to enable those mentioned to push paper with their worthless college education.
The demand curve has very little to do with outsourcing. Sure, it is a component - reduced employment opportunity leads to some reduced spending. The correlation would be clear only if people lived within their means. Most Americans have been living on credit for 20 years. As available credit or access to credit lines decreases, such goes consumer demand.
We have the fed to thank for declining growth. People have been high on cheap credit for years and glutonous with their consumption. As their credit goes to hell, or they finally reach the tipping point where the compound interest of their revolving accounts outruns their income potential, we have a mess. We are walking into that mess, and have been for five years.
