France and Germany are industrial powerhouses that are ruled by unions. Much more of their GDP comes from manufacturing than the USA, and dramatically more than the UK. It's absolutely possible to build a harmonious and productive system.
It doesn't seem to work the same in the anglosphere though. Unions in Germany at least seem more like guilds, they engage in collective bargaining but also do a lot to ensure high quality work from their members. Less need to focus on the owner/management and more need to focus on the public/customer side of things.
Anglo culture is probably more atomized, with different effects of collective bargaining as a result.
France has smaller manufacturing than the UK [1], neither France or Germany has never been "ruled by unions" the same way that the UK was in the 70s [2]:
> _The most egregious example of waste was the coal industry, hence the strikes. The tax payer was subsidizing coal to the tune of £1.3 billion a year which was real money back then, just under 1% of total national GDP, not including the increased costs to power and steel industries that were prevented from using cheaper alternatives. When the mining union leader Arthur Scargill appeared before a Parliamentary committee and was asked at what level of loss it was acceptable to close a pit he answered “As far as I can see, the loss is without limits.”_
You are just straight up lying at this point. Even in France, unionist lawmaking is one of the reasons _why_ France has so little investment and manufacturing, and Macron was elected on a platform of trying to break it up.
