It will destroy the United States as a leading economy and superpower.

Think about it: China draws mainly on the talents of the best of its billion+ population. But America has had its pick of the best of the world's 8 billion people. Until now.

In itself, no, of course not. But it's part of a much larger pattern which together blow apart that whole "great American melting pot" thing that seemed fundamental to the country's prosperity.

It's not a dumb thing to say. The US is built on immigration. Making immigration harder will lead to the next big industries not having a focal point in the US. It's also not as simple as letting college grads get green cards. It's often second or third generation immigrants creating more economic prosperity. Attacking higher education and now immigration is basically destroying the US a decade to a generation from now.

Death by a thousand cuts.
