>try to unionize next time
Amazon had a whole paper about how bringing migrants and diversity makes unionization less likely and successful. It's part of the point.
Also it's not just the US. Here in Europe it's the same. Hell the government spent it's money trough the employers org training Moroccans to become programmers to then bring em in. I knew a fair few programmers who believe this is all just for low skill low paying jobs as if paying better wages for those is impossible and as if those deserve to be undercut. The weird thing is how this kind of plainly rightwing economic rhetoric is often masquerading as left wing.
