You left out legal immigration, which is a bigger threat than illegal immigration. Every ten years we have what amounts to an amnesty with 1.2 million legal immigrants entering annually. They are essentially the same kinds of people coming illegally, i.e., poor, uneducated, and unskilled.
I’m all for going back to pre 70s immigration policies, and expecting immigrants to contribute to the economic and intellectual progress of the US, and adapt to our culture. It isn’t forgotten by me, but we need to knock some common sense about illegal immigration into the dying minds of America before traumatizing them with the bigger truth of immigration damage.
