The open-border types love the "nation of immigrants" platitude, though the USA is more accurately described as a nation of settlers, fortified by several assimilated
waves of immigration.
Waves, of course, have a beginning and an end, unlike today's model of open-ended extended family chain migration and winked-at illegal migration. So now's there's no wave, just an endless torrent, which helps make assilation passe because there's no lull in migration, and the numbers are great enough to basically set up colonized areas (additionally multiculturalism holds that assimilation is akin to racism).
Well there is a way to end chain migration. Abolish it.
Specifically, abolish the adult parents and siblings of immigrants from automatically getting in, or getting at the head of the line.
That's what was in the Jordan commission's report.
What's the status of the support on that?
