> I’m predicting that the uncertainty and discouragement of H1-Bs will lead to a destruction of jobs in the U.S. and a suppression of salaries as high quality software engineers don’t move to the U.S., allowing the center of gravity of the industry to shift out of the U.S.

Statistically speaking if you take a bunch of low-mid level salary / skill folks and move them out of US, the average salary should increase no? R&D jobs in countries like India is still low compared to US. These are the high skill and pay jobs and they will continue to be here.
