OMG. Appealing to altruism is an act of suggesting future shaming – of shaming pre-shaming… That’s why it works. They tell a half truth and suggest the rest.
Some groups are just really, really, really good liars. They have weaponized lying in order to take advantage of altruism.
Gypsies and Desert Arabs: set up camp near by, remain mobile, with little or no fixed assets, and conduct raids, then return to camp.
Other groups conduct theft by redirection: incentive to break norms.
Other groups conduct theft by obscurant fraud: financialization.
Some groups conduct theft by ‘farming’ a population (statists and such)
Scary when you just reduce human behavior to productive or parasitic.
