Nobody is deporting them (even Trump admitted that); the fact is the elites need a servant class and Americans won’t breed them (too many of the few American children born today will provide 0 productivity for anyone).
In addition, these “dreamers”, their extended families, and illegals as well, are all being trafficked here to populate a dwindling country. Asia has two countries with over a billion people each, and we have a third of that; in consumer-driven economies, that is critical. Elites need people not just as workers, but consumers as well - of all things (especially housing and public education, to keep our government worker caste employed.
There are a lot of children been born here to unwed mothers but the guberment supports them on welfare and keeps them uneducated-read non workers— so they have an excuse to bring in illegals.
Excellent points!
