How many, how expensive, and how much is this offset by others who come back and pay taxes?
I have seen a lot of freakouts about birth tourism since the recent SCOTUS ruling and I haven’t seen anyone give even the most cursory overview of the actual scale of the supposed problem. It’s purely an emotional reaction.
Usually birth tourism is done by wealthier foreigners but that foreign wealth is not visible to the government so they end up qualifying for welfare.
