being authored by prominent immigrant advocates. And one doesn’t even
need studies, as the exploitation is clear from basic economic
principles: Due to the de facto indentured servitude of most H-1Bs,
they cannot get higher pay by changing employers or by threatening to
do so. Thus by definition, on average they cannot get as high a salary
as they would if they were able to move freely about in the labor
