An underdiscussed downside of Third World immigration is that they move to high productivity areas, where they crowd out (via housing) and eventually drive out (via behavior) the locals. In immigration-heavy countries, people move *away* from economic opportunity!

This is obviously bad for the locals, who miss out on potential upwards mobility, but it's also bad for the country in general, since in all of these countries the locals are more skilled on average than the immigrants.

This also has the effect of making immigration look better in the stats, since they have higher relative wages/pay higher taxes than otherwise as they occupy high-productivity real estate, that, in the counterfactual, would be occupied by natives.
