I suggest they unionize, demand seats on the board for their unions, and crush excessive C-level compensation. Moving on just moves the exploitation to a new kind of job.
Yup every time I see H1B I replace it in my head with tech slave. They're paid, but the deck is so stacked against them they effectively cannot refuse anything. ANYTHING. A well informed H1B worker might score a chance at permanent residency for some of the abuse they suffer. But mostly it's just years of abuse with very strict rules to get their residency.
