> The least the US could do would be to show a little more gratitude by guaranteeing them permanent US residency after they graduate, but they don't even get that—many people are kicked out of the US, where they've spent most of their adult life, when they wash out of the academic pipeline.

And they often have no choice but to work in academia too, because Academic H1B are lottery exempt but not Industry H1B and they aren't transferable. Pretty messed up.
