This wasn’t a news story, it was a bunch of unsubstantiated rumors.
At worst, I got the impression a few of the immigrants might have sub-par credentials, which is a problem. But that doesn’t mean there aren’t plenty of well trained immigrants who are happy to work without trying to extract rents through a union.
Then you need to go back and read the story again. It talks about many without verifiable credentials or training at all. And many more with sub-par training and little experience.
But why would that be a problem for you? If economics is the sole deciding factor than the sooner they get rid of the high-paid gringos the better. Right?
