Except if enough people follow those "It's fine here, you are protected by the law and it's much much worse elsewhere, be happy with what get"-argumentation. Then the will probably regress because companies have a strong interest to produce cheaper than those in places where there are less regulations but they loose any interest in workers rights if there's no protesting working class. And companies interest, trough lobbying and so on, quickly becomes the governments interest.
I find that incomprehensible.
What is the replacement for that employee safeguard then?
Interestingly, as in Scandinavia (Norway, Sweden, Finland, Denmark and Iceland don't have minimum wages either), collective bargaining agreements consensually worked on by labor unions, employers and local governments. There tends to be base sector-, industry- or trade-specific agreements. Other comments[0] indicate Amazon apparently does not care for any of these.
