I hate when people say that Mansa Musa is the richest man of all time. Just because he had gold? So what, he happened to have a lot of gold in his territories. I think that is a rudimentary way of assessing wealth. The British and Roman Empires surely had less gold, but what about their holdings in land and other resources? Their armies? Their tax-paying citizens? What about the huge amount land controlled by Genghis Khan?
This is like saying "well if we assess the value of salt in the medieval ages (worth its weight in gold) then Morton Salt is the richest company in America because of all the salt it has! Stupid way of calculating wealth. Now I'm not going to claim that I know who is the wealthiest leader in history but it sure ain't this shitbird.
