> Why should a country not be permitted to prohibit you entry if you don't add value to said country? That's what sovereignty is all about.

The problem is that capital flows more or less freely but labor does not.

Fully agree there needs to be tighter capital controls. Capital should be a second class citizen to labor.

This line of reasoning is not compatible with Birthright Citizenship. If sovereignty is all about prohibiting entry to people who don't add value, why is it not also about kicking existing people out who don't add value?

The prime responsibility of the sovereign state is to maintain the social order. Deporting the children of citizens and breaking up their families is a remarkably swift way to break down the social order. This is basically sovereign suicide.

Plus I think the rest of the world would have problems with a country dumping unvalued citizens on them. Being stateless is no joke - and besides, where would they deport to? They are citizens.

In this analogy, your home has millions of rooms that you're renting out. The people arriving in your home are paying just the same as the people who have lived there all their lives. Are these new arrivals adding any less value?
