I remember a class in high school....religion, I think, with our socialist priest teaching...where as part of our instruction in "social justice", the world was reduced to a village of 1000 people. The usual: 40 people had most of the wealth and used most of the energy, etc.
There's a basic distortion between that model and reality. A tiny matter of scale. But it served its guilt-making purpose.
I am aware of the limit and tendentiousness of these kinds of models as I note that in a contemporary USA of 100 people, 13 of them take up (and drain) hugely disproportionate amounts of energy and money and psychic space and Sturm und Drang, while returning....what?
