> Inequality is getting smaller in global and it is an empirical fact.

I acknowledge that inequality is getting smaller between averages of different countries, but is it truly getting smaller between individuals (that's what actually matters)? I don't think we can ascertain that, because I think Piketty would have included the historical data if he had them for developing countries.

> Anyhow, his theory has serious flaws

If I understand the critiquing author's argument correctly - is he saying that facts stated in the Piketty's book contradict his own toy model? Maybe then his model is flawed for whatever reason, but that's not a flaw of Piketty's book.
