The job exports also affect another measure of how the economy is doing: productivity. That's essentially the Gross Domestic Product divided by the number of employed.
Productivity appears to be going up, but all is not as it seems.
When Levi shuts their last US factory and fires 2,000 workers, the company contribution to the GDP remains the same but there are that many fewer workers so productivity "goes up" even though nothing really changed (at least not for the better). Add the 130,000 H1B workers that are not in the country now and you get another "productivity boost." And the millions of manufacturing jobs gone forever lift the measure yet again.
The US is well on the way to becoming even more of a service economy than it is (80%). Your grandchildren may have to look forward to a future career of waiting for cruise ships to dock, hoping there are going to be a lot of tourists, if current trends continue.
