Unsubstantiated.... Hm, your comment implies that this parade of people is deliberately ignoring QoL improvements. I think this is not the case. What's important is to remember that everything is relative. For sure QoL has improved significantly. But so has the relative share of wealth of those who already are wealthy.

Look at wealth, not income measures and distribution, let alone how much wealth the richest people consistently added. The pace of this growth outpaces wage growth and has done so, for a long time.

So where does QoL get you when you realize the system you're engaged in is fundamentally not equitable by design and that a small elite has basically decoupled itself entirely from the rest of the world?
