At least for Norway, this is not technically true, but it also doesn’t matter.
Unions will run surveys across their members every year, and as long as they have enough members to have bargaining power, they also have the data. So they don’t really need all wages to be public in order to negotiate.
What is public in Norway, is the total taxable income of individuals. This is meant as a measure against tax fraud, and also an annual source of entertainment as you look up local and national rankings of who paid the most taxes, check that you’re still making more than your middle school bully, and so forth. But total taxable income can contain more than wages, so that is not really the number you’re referring to, and as mentioned the union has better data anyway.




I don’t think we’re contradicting each other. Sometimes the manufacturer themselves (or other Chinese entities) will be the ones creating the spec.
It also makes sense that the trash products, which compete exclusively on price, will mostly be coming from the area able to manufacture products for the lowest price. But that doesn’t mean they aren’t also able to manufacture higher quality things when requested to.
