The US doesn't want indiscriminate population growth. It wants white people that were born here to reproduce more.
Does it? It sure costs a whole helluava lot. I mean, there's tax credits and things, but it's not at all cheap!
I think capitalists just want cheap labor. The US itself doesn’t have a unified position on population. Plenty of people want a population decrease because they feel everything is overcrowded.
"The US" as a whole definitely does not want that, just the deeply unpopular white nationalists who have their hands on the levers of power at the moment.
As an aside, it's hilarious that they try to brand themselves as "Heritage Americans" since "Native American" is already taken.
