It seems par for the course for internet posters.
> I just dont think it is reasonable for people to assume they are more knowledgeable
I think the position is "this does not make sense, and I am surprised they did this."
> so they must be stupider than me
Even setting aside how they might be playing 4D chess while us chumps are playing tic-tac-toe, "stupity" is quite different from "ill-informed". It is also different from "arrogant".
Was McDonald's "stupid" in trying to enter Denmark as they did?
> They know the long term costs of union agreements, and if they spread to other countries.
How do you know that?
IF Metall also has lawyers and cost modeling, and more experience with the Swedish labor market.
Aren't you being arrogant in thinking that after 2 minutes of reading about the topic that you know better than them?
Tesla "claims that it doesn't sign collective bargaining agreements anywhere in the world" - are you really sure that decision was made with lawyers present who understood the Swedish labor market?
> some posters are quick to believes they have a better understanding of the tradeoffs Tesla faces.
Saying "it does not make sense" does not imply the person making the opinion has a better understanding, only that it does not make sense.
