The Founders utterly failed when it came to “birthright citizenship”.
No sane nation in the world would have such a policy and hope to survive.
It was not the founders. The 14th amendment created this. It was passed due to the Democrats (southern states) declaring that due to the fact that slaves were not citizens prior to being freed they were still not and their children were not due to the parents not being. Which meant they could not vote among other issues.
