The way this generally works is that people putting forward a position contrary to what is generally accepted need to support their position, not the other way around. You’re the one claiming that black and brown folks is poor because they’re dumb and white folks is rich 'cos they is smarter - provide some evidence that isn’t pulled out of a random ass somewhere.
I could, but I can’t be bothered, quite frankly. It should be pretty obvious to anyone with a basic education which parts of this thread are sensible and which are tosh.
Well, a conclusion drawn without a recogniseable methodology isn’t really a conclusion , is it?
I’m not giving up on anything apart from the opportunity to spend my spare time giving you a basic education. Read some history books. For pretty much the whole of human history the wealthiest states in the world have been either in Mesopotamia, Perisa, India, or China, with the Levant and Egypt occasionally getting a look-in. The exact leader-board positions have changed occasionally, but Europe has not had much of a look-in until recently.
What are you basing your high opinion of the Romans on? Exactly what did the Romans achieve in terms of technology, organisation or wealth that was superior to the achievements of the Parthians, Indians or Chinese? Most of their wealth was drawn from control of the more advanced economies of Egypt, Anatolia and the Levant, or from using slave labour to extract raw materials - are you now arguing that agression, looting, corruption and extortion are signs of a high IQ?
What is the average IQ in China today? What is the average IQ in the US today? What is the average IQ in Nigeria today? What is the average IQ in the Netherlands today? What is their current GDP? Methodologically sound peer-reviewed cites please.
You don’t seem to understand how this works. You’re claiming these two have a wonderful new insight into the functioning of development economics which the entire academic and business establishment have completely missed, but which is pretty universally derided as being utter twaddle. You get to back up your opinion in a way that convinces the skeptics. Otherwise your pet idea gets dismissed as being a waste of time, and you get dismissed as being either ignorant, racist, or both.
