Market forces!? No it’s the destruction of worker power through artificial abundance of low wage workers. In Holland we have a union of house cleaners and legally protected trade standards (cao) sadly the amount of people who take part in protests is small - progress is non existent or devolving.

That’s nothing compared to polish farm workers who don’t even know their rights to even request a state provided lawyer to bring their employer to court.
But the fact still remains that immigrants who don’t have the same rights create tthe conditions of a lower class that dare not ask for more.
Just like schooling is valued, so should dirty or physically difficult jobs be rewarded.
