The countries cited are extremely stable. Arguably far more stable than the US.

That said, we can bring in the rest of Western Europe if 5 countries aren't enough of an example. They have union participation rates between 10% and 50%, median around 20%. The thing is, they have much larger proportions of their workforces covered by collective bargaining agreements - France for example is at 10% union participation yet 98% of labor covered by bargaining agreements.

Western Europe and the Nordics combined = ~400 million people, bigger population than the US, and far more diverse, so the common refrain of "small homogenous population" doesn't hold up to scrutiny.

Of course, all societies so far have eventually been unstable.

We can just choose whether our unstable society will be a vindictive one that prioritizes punishing wrongdoers over the wellbeing of the whole, or a pragmatic and (as a nice bonus) compassionate one which prioritizes the wellbeing of the whole over a puritanical urge to purge the unworthy.
