That's not true because no other country is even trying to take the lead, economically speaking. China is the only country that pursues innovation nearly as aggressively but they're not a desirable immigration destination. Canada and European countries are in the best position to step up, but they're not doing so other than being more welcoming than the US in accepting skilled immigrants. The economic incentives (capital markets, risk-taking, business-friendliness, talent density) haven't changed at all and if you're good at what you do, the US is still the best place in almost all cases. Enough that it's still often worth moving there despite how immigrant-hostile the country is.

Nobody else is brain draining, correct. But neither is America. That cedes a comparative advantage.
China’s entire battery and solar platform is built on tech invented in America. They’ve since taken the lead on truly remaking modern manufacturing. But in an alternate world, A123 stayed American.
