For most people in the world, they are quite a bit richer than their ancestors, even by 50 years ago.
In fact, the number pulled from poverty over the past 50 years is astounding.
Even in rich places like the US, the poor today are vastly richer than 50 years ago. Median wages are at all time highs as well.
So how do you conclude "for most people" (which I take to mean at the very minimum more than 50%) "the economy is not working for them." Which people are these? How do they compare for income or assets or access to things to their ancestors?
