Foreign workers (fw) who work for less $ than the Domestic worker (dw) drive down wages. In this case fw is benefited by making more than they would in native country, while dw makes less than the old rate.

Paying old rate generally means dw keeps old rate, while fw makes nothing. This is the inverse where the dw is benefited at the expense of the fw.

If all people are equal who should recieve the benift?

What's the utility to people in dw society of providing benefits to fw? This has happened across broad industries and dw through their governments have signed trade deals that usually include retraining for the workers affected. Otherwise, dw and their governments end up subsidizing the costs of corporations making bank which has so little social benefit that it's really not normal to allow it to go on.

It's not a free for all in places like India to allow fw to displace their dw or drive down their dw salaries. The US is getting taken for a ride with these policies.

dw's society can produce goods at lower cost than without fw. But really there doesn't need to be any benefit to dw's society unless dw's people consider themselves privileged and deserving a better life than the world's poor simply because they happened to be born into it.

The million dollar question is: which ones are you entrusted to represent?
