Does anyone actually think it’s pro-capitalism? Though the social psych equivalent to this is just the concept of the harvesting dilemma and the main lesson is generally pro government regulation (regardless of economics). Social dilemmas like this apply to any common good everyone benefits from, be it air quality, military defense, public parks, public safety, etc. (when explaining, I use a few right wing examples too, even if I am a bit ACAB myself lol).

Basically, they simply don’t exist without some form of social agreement not to be a shitty greedy asshole. Government being the most obvious way to control that.
