> It's hard to understand why in the US many people see it as norm. Just have a legal immigration system that works. Historically there's all kinds of things going on, but the industrial revolution massively increased travel and softened national borders almost worldwide right up until around WW1. This time period coincides with the US becoming a global power. In the modern time, there's two more reasons, both cynical: 1. It lets them have an underclass such that they can away with lower pay and lower rights, which conversely also allows all the native-born to earn more than they otherwise would have because someone has to do these jobs that have yet to be automated. 2. while also demonising that group for bonus points in elections. Everything breaks hard the moment anyone with power mistakes the kayfabe (demonising the vitally important underclass) for reality. Letting yourself be one whom politicians can score points out of, encourages the election of politicians more likely to make that mistake. The people anyone really needs to worry about? They've got official passports and visas and naturalisation (in the US's case, Musk) or are native born citizens (Trump), and yet are working against the national interests, and in some cases even directly for foreign governments (e.g. https://www.justice.gov/opa/pr/active-duty-soldier-arrested-and-charged-espionage-and-export-violations https://www.justice.gov/opa/pr/active-duty-soldier-arrested-...).
