This is an important thing that was recently addressed by the new $100,000 fee to sponsor an H-1B visa. It is especially impacting Indian tech workers in the US [1] since the types of roles that InfoSys and other foreign tech consulting firms are staffing do not meet the bar of "leap forward in capabilities". A US company is welcome to sponsor (and pay for) a visa for a truly exceptional worker. But not just anyone because they're cheap and minimally-capable.
