The idea that international socialists have that domestic labor conditions are made worse by a lack of protections for foreign workers (rather than the presence of the workers themselves) doesn’t pan out if you look at Canada; it’s quite rare for status in the country to be tied to a particular employment agreement, so immigrants are free to leave undesirable employers, but wages are substantially lower there due to the country having accepted about 3 million immigrants and temporary workers in the span of the last ten years.

I don't really see how this relates to my comment about the connection between benefits and employment.

> wages are substantially lower there due to the country having accepted about 3 million immigrants and temporary workers in the span of the last ten years.

Do you have any evidence of that causal connection, or is that just an assumption? The US also accepts large numbers of immigrants and temporary workers.
