[WS:] You seem to be missing the point. The value of Diamond's book lies in dismissing the culturalist ideology in accounts of economic development (i.e. beliefs that "superior" values such as hard working, work ethic, entrepreneurship, leadership, family structure, legal system etc.). Diamond counters that by showing that "civilizational advancement" was, for the most part, luck. Those who landed on premium real estate with a lot of usable resources advanced quicker than those who did not. It would be hard to find a more powerful critique of the culturalist bullshit proposed by assorted conservatives and idealists.
Yet, your interpretation not only dismisses that critical potential; but reverts back to the culturalist ideology only with a reversed sign: Europeans - bad culture, non-Europeans - good culture. You are really shooting yourself in the foot.
