While something like that would help mitigate the abuse vector (although the number would have to be higher - $150k is not much in Bay area tech), it introduces its own set of problems in the other direction, because now only the most profitable companies will be able to hire foreign labor. I know that's the point, but as long as the market fails to account for positive externalities, positions like nurses and teachers will be systematically undervalued, even though it's much more valuable to the country in the long run for expert labor to land there.
