The offshoring of high tech skills in computer related sciences will soon turn into a flood as more and more state universities loosing funding to instead support building and staffing more prisons and more draconian law enforcement necessary to maintain the status quo, more tax deductions for the 1%, and more special tax breaks for corporations, all further driving up the cost of education and sending the best faculty overseas and increasing the costs of tuition. Improvements in world-wide networks will only facilitate this trend.
This shift in investment is creating foreign universities that are increasingly more and more competitive with US universities and as things are going now we can soon expect the most advanced research, such as that in particle physics, stem cell research, high speed train and subway technology, and robotics, to be dominated by non-US based enterprises. Its largely a function of ideology on tax policy, which says lets pay as little taxes as possible (especially for the 1%), and consequently invest as little as possible in education and leading edge research (and many other things as well, evidently except military spending, fossil fuel production, and good old fashioned special interest).
Ironically, the solution proposed recently by Saunders, would largely solve this problem by providing free college education by imposing a Wall Street transaction tax that would directly fund education of all kinds, thereby allowing the best and most creative to develop their talents. American exceptionalism notwithstanding, the reality is that human minds and talents aren't so different among countries (the differences lie predominantly in the consequences of geography and cultural history). Consequently, progress in education and technology is predominantly a function of the laws of large numbers and there are simply many more foreigners than there are Americans.
Of course commerce has been global since the late 19th century so large corporations can take advantage of local differences in talent and wages so no one should expect programs like H1B visas and other forms of special interest legislation not to emerge. The fact that they thrive is ultimately a function of lowered US investment in education and research of all kinds and sadly, a modern GOP and a significant fraction of the Democratic Party that have bought into the politics surrounding the ideology that lower taxes for corporations and the wealthy will trickle down to to improve the lot of the rest. Although it may well be true in some cases, the amount of its success is far way too small to overcome the advantage to other nations that invest more in education and research for the broadest possible segments of their populations.
