If you look globally at countries which have issues with their large social services, they're almost all mostly homogeneous and declining in population, especially among the young. Which makes sense if you sit back and think about what social services are typically offered and where the money comes from.
Of course that might require some changes to make it actually true illegals don't use state benefits. You need to cut off WIC for illegals, public schooling for illegals for instance before they will actually not be using public benefit. Also their children become legal via jus soli.
The obvious down-side is that those citizens / legal residents who have the skill level of illegal immigrants (sad, but commonly true) will see their real wages depressed and more competition for the job.
I want more immigration I just don't want companies able to abuse people/people be treated any different/having less rights/power than anyone else in American. I think I'm just going to be full 'open borders' now because otherwise it always ends up with trash manipulating things in racist/corporate power way.
Libertarians assign culture zero substantive value, viewing people as fungible economic actors. Like many libertarian assumptions, that one isn’t grounded in empirical observation.
This seems somewhat incorrect to me, as people change jobs and with it, culture, basically all of the time.
We have strong evidence that deeper cultural, everything from attitudes towards saving, government, and social trust, persists for generations after immigration: https://www.nas.org/academic-questions/36/2/rethinking-immig... (“The authors found that forty-six percent of home-country attitudes toward trust persist in second- and fourth-generation immigrants—in the adults whose parents, grandparents, and great-grandparents were immigrants. People from high-trust societies, like Sørensen, transmit about half of their high-trust attitudes to their descendants, and people from low-trust societies do the same with their low-trust attitudes.”).
You can see this just by going around the country. Scandinavia has much higher social trust than Italy. The upper midwest, where Scandinavian immigration dominated, has higher social trust than NJ/NY, which saw mass immigration from southern Italy.
These deep-seated cultural variations, in turn, have a strong impact on societal prosperity: https://news.harvard.edu/gazette/story/2020/09/joseph-henric... (“One of the points I want to make is a lot of the big institutions we think about, like Western law or representative government, actually flow, in part, from the way people think about the world.”).
