Some might return to invest in the USA and move or start businesses here.
At least at that kind of money they aren't deadbeats.
“Hard to tell if this works out in the long run as good or bad for us”
You have to be kidding. It’s great I guess if you want a multicultural mess like California where American culture is disappearing.
The whole notion that immigration from China and Latin American countries is beneficial to the US is nonsense. These countries pull billions out of our economy and send it back to their home countries in remittances. In the case of Mexico it amounts to $33 billion a year. And in most cases this is after their people, the great majority of whom are here illegally have received billions in free health care, free education, etc. They only see America as a giant ATM and Americans as fools.
