With all due respect, Mr. Eskow, the cultural aspect (Gordon Gecko) is the antiseptic administered prior to the shot!
The shot is NAFTA, CAFTA, and every other trade treaty that not only makes it possible for corporate firms to relocate to nations with far lower labor standards, but frequently provides them with financial incentives for doing so!
If a company's CEO and board of directors deem it cheaper to relocate to Mexico, then workers will have a very weak bargaining position.
Unions were undermined largely on account of Trade Deals. The cultural narratives that prized the rich were part of the calculus... but hardly the causative element.
I find the absence of mention of this particular factor troubling... with TPP and TIPP breathing down the world's workers' necks.
