This a big news to me.
These are called dialects. They want a divided workforce so that no one questions them about poor labour laws. E.g Amazon and Tesla
Please don't create accounts to break HN's rules with.
It is possible to be impolite, ungrateful, obnoxious and correct.
Ie, cardholding need be completely blind to recruiters. Ie, instead of `Do you have work authorization?` as the first question asked [no less], it need be enforceably ILLEGAL to try fish information about it.
In practice that can't be fully done without also blinding a lot of other related things. But having Single-Market enforced by law will certainly reduce the pay gap found today in lvl-to-lvl comparisons (top ppl of country A vs the same of country B; bottom ppl of country A vs the same of country B).
re "vent" "disrespectful"; I believe their comparison is meant to be neutral and nonhurtful, albeit not of PC enculture.
