If you look at the charts, it seems that if the US is a shithole, then Canada is twice the shit hole, and France and Germany are twice that.
In fact, it doesn’t appear that there are any non-shitholes using this metric.
I think the US should facilitate immigration by probably expanding the H1B 10x and reducing the period for a green card and also overturn Euclid v Amber and NEPA (with state level CEQA style to follow) but the reality is that even an immigration-resistant US administration is far more popular than any other country as a destination; and that’s probably simply due to the fact that it’s the one Western economy that is still dynamic despite everything.
