I'm not sure I buy that. Say you're tasked with planning and building a whole new city in an isolated place. Do you want to bring along 10,000 randomly-selected Bangladeshis, or 10,000 randomly-selected Danes? As a Bangladeshi myself, I'd choose the latter in a heartbeat. I think you can fairly blame circumstance for it, but at the end of the day, Bangladeshi culture has a higher tolerance for corruption, theocracy, opportunism, etc., than European cultures I have experienced. (But I'm biased--2/3 of Bangladeshis think I should be executed for apostasy. The odds are not in my favor!)
Also, in Denmark, the standard sentence for murder is like 12 years, while in America you can get 12 years for far less. We voted for that. Doesn't that make Danes better than Americans?
