> What I am saying is that the global average getting better is a skewed and rather meaningless metric. The fact that 100_000 EU/USA citizes are slighly better off at the cost 1_000_000 asians -- random numbers to demonstrate how an imbalance can be evened out -- does not mean that humanity's economy is getting better. Not at all.

I'm pretty sure Pinker doesn't use average income as a metric. I'm not really sure where you're getting that from. The relevant metric is number of people living below the poverty line, which is a metric which doesn't have the same issue.
