The funny thing is I bet ending birthright citizenship is an amendment that could actually be passed. You don't have to be a virulent racist to think the context has changed when you can get almost anywhere in the world in about 24 hours.
(I'm not sure where I stand on it but I can at least see an argument for revisiting the question)
If you're late enough in your pregnancy that giving birth during your vacation is realistic, you're likely to be refused boarding or turned back at the border. Birthright citizenship tourism is much smaller of an issue than stated.
Because US has no other form of becoming a citizen other than naturalization.
Also frankly it's a bit silly when you are born to two residents of a country but don't become a citizen. Why does it matter what passports they hold if they live and work in america like american citizens? People being born on the same soil being given second class citizen treatment is pretty despicable imo.
