I don't see why this "massively sucks". Obviously, the American people, and the government they elected, don't really want these smart people in their country contributing to their economy, so there's other countries (the ones with friendlier visa policies) where they're more welcome and they should go. You can claim that Americans are shooting themselves in the foot with these policies, and electing people like Trump, but if that's what they want to do...
