>But the gains have BY AND LARGE gone to the wealthiest individuals and countries.

This is simply false, the average Chinese or Indian is incredibly better off now than they were 100 or 500 years ago. In fact for the past decade many of the wealthiest countries (many Western European countries, and Japan) have seen barely any growth in living standards at all, GDP-per-capita growth has been concentrated in developing countries.

It is correct. The richest 10% now earn 53% of global income. The top 10% average income/bottom 50% average income ratio has went from 18x to 38x in the last 200 years.
