This a question of philosophy. I agree, philosophically. However, if you’re just looking at data, educated immigrants are an economic gain, while uneducated ones are an economic loss.
However, change the algorithm. If there were less public expenditure, the values would change. Different labor laws, values change. Data are just a snapshot, not a prophecy.
If your - and my - ancestors existed to be an economic gain we’d all be farming 2 acres in Belfast.
Immigrants belong in America regardless of where they come from. This is the promised land. Anyone can come here and the generations beyond them will achieve the thinfs thar I habe oe Ben Carson has.
Shutting people out because their country is a bit poor is bullshit.
