Yes, by doing the poorly paid hard labor jobs the locals didn't want because they can chill on welfare, you know, the whole "muh labor shortage" bit.

It's not like Germans, Dutch etc or the "new europeans" they imported, were rushing to wiping the asses of their elders in their own care homes or picking fruit all day in the sun on their own farms.

What was left to send home after that wasn't "significant" by any stretch, after paying taxes, rent and CoL to further boost the local economy and the wealth of the local asset owners.
