Yeah, but the 14th Amendment remains pristine in relationship to the current problem of illegals in the country for purposes of giving birth for purposes of gaining things from the country (or otherwise).
An Amendment can be clarified by other actions, updated. That's the beauty of our Constitution...
The correct solution to the issue of "anchor babies" is to "cut the anchor chain". In most jurisdictions, parents can lose their parental rights in cases of child neglect or endangerment (or for less sometimes). The crimes that qualify for revocation of parental rights should be expanded to include having a baby while in the country illegally.
Take the citizen babies away from the illegal parents, adopt them out, and then deport the parents, and the issue of "anchor babies" will disappear. Guaranteed.
