Totally agree. We should have <1B people living like kings, not 10B people living like peasants. A lot of environmentally unsustainable things become perfectly sustainable if there are fewer people on the planet. Like, we shouldn’t have to be worried about the impact of beef production or overfishing - the planet should be able to sustain the number of humans that want to eat those things. At 8-10B it obviously can’t.
It’s worth noting that Americans also must spend that income in a similarly-inflated market, so it doesn’t much matter what their salary would be worth in, say, Uganda. I think any such comparison of global wealth runs into these sorts of issues.
Someone earning in the global top 10% may not be able to afford a house locally. Someone earning in the top 30% may not be able to afford rent and food at the same time in their locale. It makes the percentile meaningless.
