I posted an article a few days ago about the changing demography with lower population growth. Here is another example of the already changed world. Our immigration debate is about the past, not the future.
We had a few big waves of immigration from specific areas. The largest was NOT the Hispanic wave; it was Germans. We also had big waves of Scots-Irish, Irish and Italians. Each time it seemed like it would go on forever and each time it abruptly stopped. Looking forward, we will suffer a shortage of labor and will be hoping for more immigrants, at least those with specific jobs or skills.
Yesterday's debate was about how to keep them out; tomorrow's will be how to attract them in.
Between 2009 and 2014, about 140,000 more Mexican immigrants have returned to Mexico from the U.S. than have migrated here, citing family reunification as the main reason for leaving.
