I am well aware of US immigration law history and the views of the current administration regarding immigration.

How does reading up on the history change how the stated reason for this pause has nothing to do with the meritocracy issues, fraudulent H1B visas, etc. that you complained about?

Do you think those labor issues will be improved after the training is finished, and if so, why?

How does your earlier comment explain why visas based on family preference are also apparently on pause as well?

Of course if we look at the history of US immigration we can easily see how for over 150 years it was explicitly set up to support a white supremacist race-based culture, which broke down with the civil rights movement and the incoherency of "whiteness" as a legal or scientific definition (are Arabs white? Are Asian Indians white? Are Chinese immigrants in Mississippi "white"? - https://archive.org/details/mississippichine0000loew/page/n7...).

With the current reactionary administration's antipathy towards nearly all immigration, except seemingly white South Africans and Nordics, it's far easier to interpret this action as deliberately gumming up the works and causing distress, rather than some systemic beneficial labor reform like what you want.

I assume that's what you mean by reading up on how we got here?

No I am talking about why a specific pause on 75 countries turned into this global pause that we all find concerning. You seem to have a wishful view of humanity as some post border utopia but that’s not how our or anybody’s laws work. If you want to go post border that’s a super interesting idea to talk about over some beers or whatever. But looking at our very standard immigration process and telling people who are concerned about curbing real fraud that enforcing our laws is racist is pretty out of touch.
