WaPo article on the History of US immigration policy. It tells a tale you might not be familiar with. It is long with lots of charts.
Excerpt:
"Migration today, again, has taken a new turn. Migrants are no longer mostly single Mexicans crossing the border surreptitiously to melt into the U.S. labor force. They are families, and they come from Venezuela, Haiti, Cuba and Ecuador, China and India. Mexicans accounted for fewer than a quarter of
migrant encounters with U.S. agents along the border in the first half of fiscal 2024.
The most explosive difference is that immigration today is much more visible than it has possibly ever been. Immigrants don’t try to squeeze across the border undetected. They cross it without permission, turn themselves in and ask for asylum,
overwhelming immigration courts and perpetuating the image of a border out of control.
Americans’
sense of threat might have more to do with the chaos at the border than with immigration itself. Still, the sense of foreboding draws from that same old well of fear. That fear is today arguably more acute than when ethnic quotas were written into U.S. immigration law in 1924. Because today, the White, Anglo-Saxon Americans who believe this nation to be their birthright are truly under demographic siege.
Twenty years from now, White, non-Hispanic Americans will slip below 50 percent of the population and become just another, albeit big, minority. For Trump’s electoral base of older, White rural voters, the prospect of non-Whites acquiring power to challenge their status as embodiments of American identity amounts to an existential menace that may justify radical action.
Immigration has re-engineered U.S. politics.
Non-White voters account for some 40 percent of Democrats.
Eighty-one percent of Republican voters, by contrast, are both White and not Hispanic. The nation’s polarized politics have become, in some nontrivial sense, a proxy for a conflict between different interpretations of what it means to be American."
