>Cooperation is really the core mechanism for societal growth
This is an interesting claim to make when almost all of the leaps forward in technology advancement came either during a war, as part of the lead up to one, or within the context of a cold war. Similar to the entryist problem, everyone demands cooperation from the United States, no one asks for partnership.
>in this case, by creating a subclass
This is literally the point of the concept of the Citizen. A Citizen is prioritized in their own country. A non-Citizen is not. Something happened with education because it feels like we have to go back to deriving the point of the nation-state from first principles.
I mean, it's a free country, nobody can make you accept an idea you don't want to. But the nativist ideas you've adopted are not considered by most Americans to be acceptable. If you go around telling people that immigrants aren't real Americans, you will not be accepted even in many conservative circles. Even much of the Trump movement views nativists as useful dupes; the Vice President and Secretary of State, for example, clearly would not welcome your theories that their kin are diluting "the voice of Americans".
And again, I'd really like you to consider the honesty of the people who've told you this is a thing. In your readings about this movement to protect the voices of people who've been here for a dozen generations, did they ever mention to you that the current President is a third-generation immigrant and the Secretary of State is second-generation? If not, why do you think they didn't?
Another thing I'd encourage you to think about: why do you think that the party in control of the White House and Congress wants you to believe that "the actual political movement with power and influence" is their opponents? Normally one would say that controlling the government makes you powerful and influential. Perhaps they're just very humble and self-effacing, or perhaps they don't want you asking too many questions about why their power and influence hasn't achieved what they told you it would.
My point about 1999 has nothing to do with nostalgia. It has everything to do with absolutely no one asking for entire neighborhoods and towns to be turned into impenetrable foreign countries. There is a stark difference between immigration that brought people like Rubio here and mass migration from e.g. Somalia, in terms of scale, context, and timeframe.
That smacks of entitlement. Yes. I know that the other side of the argument also smacks of entitlement. But I believe I have the 14th amendment on my side.
Also, there are a lot of assumptions baked into your statement. If you think that everyone here who can trace their roots back "a dozen generations" has your ideals, well, I've got $24 worth of trinkets to sell you.
Conversely, if you think that everyone here who is newly immigrated does not share your ideals, well, I have more trinkets.
The Mythology of America that I bought into was that it was a welcoming place where you could re-invent yourself in a way that was rarely possible in the country your were leaving.
And yes. I know it's a mythology--with kernels of truth to it.
But you have your own Mythology--and I find it unpalatable, both to me and my immigrant parents.
Sounds like a good thing to me. More diversity means we can incorporate the best ideas from everyone, instead of a select few. But I suppose not everyone likes to try new things
