They actually are, but the Anchor Baby policy may be changing soon, and for good reason. Way back when, the nation needed bodies. Before we booted the Monarchy, they'd offer free lands to anyone who would relocate to the Colonies. Early in our Founding, our westward expansion had very similar policies.
But there were less than 1 billion people in the world before 1804. The world now has 8 billion, and most major nations have overpopulation concerns, not under-population. Obama's Science Advisor famously wrote in the 1960s that America was already grossly overpopulated, and we would no longer be able to feed itself by the time we hit 225m in the year 2000. We hit 225m in 1980, and we still are the largest net food exporter on earth even at 330m.
Please, spare me the twisted history lesson. It has little bearing on the current situation.
Adults criminally sneaking into the country do not support American Freedoms and notions of the Rule of Law.
They are here ONLY to take.
When they arrive in time to deliver their offspring, then the child inherits their criminality, not US Citizenship.
I know that is not a popular notion, and has not been ‘policy’ for a very long time.
That does not make it less real.
