It’s how their middle incomes could afford so much.
Only because it’s widely thought that their incomes had to come from exploiting those beneath them, instead of taking it back from those above.
You’re being exploited by someone who tells you that’s what it takes and you just have to look below for someone less fortunate than yourself and exploit them. Instead we should come together with those less fortunate and collectively turn our attention to those who have been exploiting all of us to take it back instead of fighting the puppet on the other hand.
