I don't think you know how it was originally meant
And you do? The 13th Amendment freed the slaves. But there was a problem in that it said nothing of were they now legal citizens of the US? Or their offspring? So the 14th was ratified to address SPECIFICALLY that. It was not created willy-nilly right after the 13th Amendment to allow for foreigners to just sneak in and have kids that became automatic citizens.
Also, it was never really considered a big issue in this country before somewhere along the way it became the accepted idiocy among a lot of people that our immigration laws are to be ignored as anyone who comes here sees fit.
"All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside."
It's long been argued that this is the key phrase, as foreigners are not considered subject to the jurisdiction of the United States, therefore not whom was meant. The language of the Amendment is a result of compromise so that it could include the freed slaves and their offspring as citizens of the US.
Many people, myself included, find it absurd that what was intended to settle the question of the citizenship of freed slaves, has since been completely bastardized in order to help cheating businesses create virtually a new and improved slave trade of sorts using exploited illegal labor.
The language of the 14th Amendment truly IS outdated since there are no longer freed slaves and any question of their being US citizens or not- the whole question it was ratified to solve has long BEEN solved, so it should be reworded more logically. It was NEVER intended to mean "Sneak in and have anchor babies, we'll look the other way."
