Howard Zinn talks about a possible revolt of the guards: http://www.historyisaweapon.co...
"However, the unexpected victories-even temporary ones-of insurgents show the vulnerability of the supposedly powerful. In a highly developed society, the Establishment cannot survive without the obedience and loyalty of millions of people who are given small rewards to keep the system going: the soldiers and police, teachers and ministers, administrators and social workers, technicians and production workers, doctors, lawyers, nurses, transport and communications workers, garbage men and firemen. These people-the employed, the somewhat privileged-are drawn into alliance with the elite. They become the guards of the system, buffers between the upper and lower classes. If they stop obeying, the system falls."
And here is the inequitable financial reality of that system given wealth is control under capitalism:

I wonder if the problem as seen by the ruling class may be that techies have their hands on the key infrastructure of modern society (including banking infrastructure)? If US techies were really well-off (e.g. all millionaires), techies might have some time and energy for creating alternatives. So, best to keep them down by making them insecure by importing cheap labor rather than train US Americans and provide them higher salaries, more benefits, and more equity. Techies may think they are doing well because they are doing better than the average US American -- but what they are paid in general does not reflect how key their contributions are these days to the digital infrastructure of control and surveillance.
I remember back in the 1990s when independent contractors got 2X to 3X what regular employees did. The H1Bs, even at prevailing wages for employees, also greatly undermined the earnings for contractors too. Many H1Bs don't really replace employees as much as they replace contractors.
