Yes, that is what I point out. Inequality is a fact of life and the natural level of inequality is what drives people to outdo themselves so as to become 'more equal than others' but inequality does not automatically equate to resource concentration in the hands of a few while the rest starve. The cited study does not much more than indicate that government structure has a deciding effect on wealth distribution. It does not in any way indicate that forced redistribution - Borrr and friends taking Gnurgh's beef jerky and half of Oogrl's rats - or elite rule - Gnurgh employing Oogrl to force Borrr to slave in the mines while Gnurgh takes all the profits - is better or worse, just that societies can be formed in both those ways as well as in ways which more resemble what is probably the best way: Oogrl can hunt his rats, Gnurgh can make his jerky but Borrr is kept from stealing and raping cave girls. If Oogrl wants some jerky he can either try to set up a business in roasted rats so that Gnurgh, tired of beef for breakfast/lunch/dinner can swap some or try to make some for himself.
