You guys have a warped view of culture and the benefits of culture in general. Like, what are you even expecting this answer to be? A list of musicians or something?
I grew up in the city, so my childhood friends were all exactly like me (typical american childhoods) except their home-life had elements of their parent's country. My friend group was a Polish kid, Lithuanian, Chinese, and a Pakistani. This was early 2000s chicago.
As a result, all of us have a better understanding of the international world, history, culture, because you would do things like go to their house and notice that everything is Polish and their dad loves to talk about polish history, for example. Or that information about Pakistan that you learn in passing over the years makes more sense in the context of their culture, for example.
And then some dum dum from work goes on saying some racist bullsht about Polish people, presented as "fact", and you realize how stupid it sounds.
So that's the benefit of knowing people from a different background. That's what they contribute. Also, they're going to be exactly like everyone else within 1 generation. That's another thing people overlook. It's just more proof that the people talking about this sht have never even met someone outside of their cult.
Without immigrants, you end up in a dead end. You cannot fix the brain of a MAGA without this. It's like trying to play chess with a pigeon. No amount of training it prevents it from knocking all the pieces off. Their xenophobia will never go away until they leave their suburbs.
Like, imagine trying to explain a specific engine part and how it functions to a man from 1750 who has never seen a car? That's what it feels like talking to a MAGA about immigrants.
And another thing, this lack of cultural-knowledge really messes with middle-American's financial opportunity. Let me put this in a language you understand. I work a corporate job in NYC doing pretty well. If you're simple minded, you're going to be poor forever. People will laugh at you for even entertaining any political stance that isn't left, even lefter than the Dems (fk the dems). If not, it implies you didn't take any serious classes in college and don't have a complete worldview. If you don't have that, how can you be trusted to do international business, where the real money is? So literally another benefit of them is that they will make you and your family more money (because of the education)
