c) I am skeptical that pg's proposal would substantially increase the number of truly great programmers who could come to the US, and I believe it would actually just increase the pool of decent programmers which is already large enough to meet demand: so the net effect would be the same companies and software being created, but less money being paid in salaries and therefore spent on consumption, which is worse both for this pool of decent engineers and for the governments which lose out on the taxes they could have gained from the distribution of money from pg and other rich investors to the employee engineers.
