there is no place to run to - alot of people I know who were lucky enough to have security clearances are piling into government work - either directly, or indirectly through government contractors and sub-contractors. that's the most stable work out there right now. all the free traders pay their salaries through their taxes now.
the problem is, any new VC money coming into the system (especially second phase funding, past the startup phase) include some component of offshore technology staff - or you don't get funded. So new business plans factor that in from the start, the jobs never appear in the US right out of the gate. I see that alot with people I know in semis - running a fab in the US for a new venture is the joke of the industry now.
