Birthright citizenship tale... Our social circle in Maskachusetts included a guy married to a Honduran. Every time one of his wife's relatives is pregnant she comes to stay with them. When it is time to deliver the baby, the relative Ubers to one of the most expensive hospitals in the world, e.g., Beth Israel. She gives birth, says the magic words to avoid ever receiving a bill ("I'm undocumented"), and, after a few weeks, heads back to Honduras with baby, birth certificate, and U.S. passport. This one family has likely cost taxpayers at least $300,000 in payments to the hospital for "uncompensated care" and more than 10 U.S. citizens have been minted. When the kids are adults they have an automatic right to sponsor their parents for green cards, so eventually this one family will be responsible for perhaps 40 or 50 legal immigrants from Honduras to the U.S.
