This isn’t exactly what the previous comment was talking about, but it’s similar. https://www.theguardian.com/world/2011/oct/14/alabama-immigration-law-workers and there’s something similar going on Florida too https://www.npr.org/2024/04/26/1242236604/florida-economy-immigration-businesses-workers-undocumented
These are my go-to articles anytime the subject of undocumented workers comes up. Personally, I think we would go back to the old model. If I remember correctly, the 1930s was when immigration started to be severely restricted; but, before that, temporary workers would come up for a season of employment and then go back home. All of it was done legally. It wasn’t until immigration restrictions were enacted that there was an incentive to stay and move their families into the US.
Go Japan! Hell yeah!
