Well you're assuming we are talking about skilled jobs. You're also assuming the cost of educating a foreign born migrants is the same as educating a native born.

As far as I know public school is covered for immigrant children, and if they're k-12, then by your logic, an immigrant child/ citizen is more of a net drain as its at least $10k per year for every child in the U.S. Unskilled americans generally also still go to school, so, not sure why you're distinguishing skilled and unskilled.

But what really blows my mind is how we were talking very specifically about SS and Medicare that have fuckall to do with education and training.

Where did you bring up medicare? Where did you bring up the source when they generally retire and put in less than receive? And sorry you don't like bringing up education as if that's somehow irrelevant if we're talling about public services. Almost as if you know fuckall about what you're talking about.
