I live in Portugal, where blaming others seems to be a national sport.

It's purely speculative arm-chair sociology at this point, but I would wager that there's a self-enforcing relationship between the proportion of time a society spends trying to find who to blame and the levels of corruption and physical and social infrastructure that sits in disrepair.

Of course, if you can blame someone else for the state you're in, and thereby shift responsibility for fixing the problem, then you can live in a crumbling society without any motivating compunction to fix things.

We hate taking responsibility for fixing things because we think doing so means accepting blame. It's the "It's not my trash" attitude. Ok, but it is your street, or your neighbourhood, or your city, or your planet. Do you want to live in a trash heap? No. It's your responsibility to make the world you want to live in.

Cooperation, as you've so eloquently put in this article, cares little about who to blame. It just wants to get on with the job of repairing our broken institutions and making things better.

I have some similar thoughts on blame and responsibility in a more economics-focused post, if you care to read: https://medium.com/the-thinkery/thats-not-capitalism-a1d99f666b86
