Can't blame 'em due to the high cost of compliance and regs...
But has anyone seen the cost of goods, labor and services decrease?
Friends in the construction business tell me the mex's put up structures very quickly... and the work is shoddy. When has new construction prices decreased? NOT.
This could probably be Googled quickly enough: What fraction of the construction industry is independent contractors, and what is associated with the corporate world? Perhaps some workers, especially day labor, are illegals, but what about construction materials? Where do the materials come from? Local forests? Where do the tools, the trucks, come from? Detroit? Where does the portland cement come from? A local geological deposit? Where do the nails come from? Great Lakes iron ore?
You see. It's more than the on site workers, whatever percentage are dragging down those wages, even independent contractors interface with worldwide corporations.
