I know it sounds weird, but if a country has a legal minimum wage it removes tools from unions since companies can just tell the unions to pound sand.
Here in Sweden we don’t have any minimum wage mandated by the government.
It is negotiated between the sector unions and employers.
Also sympathy strikes are legal here.
Whenever there have been talks about introducing a minimum wage in Sweden, unions have allways reacted negatively, as it would effectively prevent them from negotiating for higher wages, and a minimum wage would easily get stuck in the past.
I know that the US and Sweden are very different, and that in the current labor market in the US, removing a minimum wage would be a disaster, but I felt as if your conclusion that minimum wage is allways bad needed a counterpoint.
