Capitalism sets up rules based on practicality and repeated interactions between people, which means that they actually make sense to follow even if you are purely selfish. In a system where the rules are based on empathy or ideology, the psychopath will have ZERO desire to follow the rules if they won't get caught, but because interacting peacefully in trade with people actually pays off they get incentivized not to just do whatever they might impulsively want.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
