There's no such thing as a "National" economy anymore -- even accepting the dubious proposition there ever was such a beastie.  When the Federal Reserve started paying banks to borrow money after 9/11 the borrowers took that money and built factories in China.  This means the money was used to create jobs in China not in the US.  The follow-on was a loss of income and the necessity of (1) lowering consumpution - defeating the purpose of monetary expansion - or (2) borrowing to consume.  

We all know what was chosen.

Eventually, tho', consumption must follow income.  If the consumers in a geographical area cannot earn they cannot buy.  The industries moving their factories will, eventually, find their profits are directly linked to wages.  

One 'gotcha' is a $50k consumer needs 5 $10k consumers to pick-up the slack but it costs 5 times as much to get those 5 consumers.  As the firms move into new territory they have no established customer base and establishing a market presence costs, as well.  And these firms will be running against Chinese (to pick an example) firms that do not have bloated fixed expenses (e.g., $100 million CEO salaries) and capital costs.  The 'Chinese' firms can provide the exact goods and services at much lower consumer cost.

Together, the firms moving their production to lower-cost countries are putting themselves out of business.
