Was thinking along similar lines. Who doenst like cheap labour? When have economies suffered because of cheap labour?

Economies grow by making stuff, making stuff at a competitive price is easier when labour is cheaper.

I’d much rather get my car washed by a person than a machine.

IMO the issue is the number of people who are net negative on the economy vs number of people who are net positive. If you are net contributing to the economy it should matter what colour your skin or passport are.
