well, most of the high tech equipment is manufactured in Communist China and other foreign lands
and most of the designers and programers of that equipment are either IN Communist China or India or other foreign lands, or they are from China or India, etc.... taking jobs in SillyCon Valley and other “American” high tech factories ... imported, largely, by the executive management of said firms so that they don’t have to hire USA citizens...(see, for example, the following article from today’s news cycle...but this problem has existed for many years, its only gotten more and more pronounced in the last four or five years but this problem dates back a long time as the “American” companies have liked the “better work ethic” of the “more productive” foreigners...)
So, with much of the equipment made overseas and then most of it designed and coded by foreign workers (both overseas and working in USA jobs)... “what’s to worry??”

2013 marked the first year that there was no net outflow of manufacturing jobs.
The trend currently in the USA is re-shoring. Something like 50% of US companies in China are at various stages of re-shoring their operations to the USA.
The long communications and supply chains are too expensive.
