People can’t seem to separate the issue of exploitation of H1B by (mostly Indian) consultancy mills to lower wages and bypass normal immigration vs the legitimate value of specialized skilled visas. You can fix one without killing the other.

It’s plausible Education might be one of the industries that gets exploited as they have no caps in the lottery like other H1 visas categories such as tech or doctors. But I don’t know enough about education visas personally.
