It varies a bit from country to country, but the overall idea is that cooperation between strong national labor unions, employers and the government can lead to a solid wellfare state for all. Some parts of our workers rights are therefore kept in collective agreements instead of laws. This is of course not a perfect system, and we regularly have problems with locally sourced super-rich as well, but most people here agree it creates a better society, even for “regular” millionaires.
One of the cornerstones for this to work is strong nationwide unions to create a sane balance of power. Much of this current conflict could be solved if someone got through to Musk that the right to organize is holier to us in the nordics than gun rights are to Americans.
I agree, let’s nuke southern Sweden into the sea before accepting them! (Assuming you are referring to the Norwayless euro coins)
