It’s been reported that the 85 wealthiest individuals have wealth equivalent to that of half the world’s population.
It’s not clear how debt is accounted for. Some rich people can accrue far more debt than us normal individuals. One might calculate the poorest person on earth has a net worth of negative billions; that person still could easily amass actual goods, insofar as “if you owe a hundred dollars, that’s your problem, but if you owe a hundred million, that’s the bank’s problem.”
Assuming, however, that there is little skewing of these figures by actual negative wealth, we can assert that the mean total wealth of the 85 wealthiest is 7,000,000,000/85 = 82,000,000 times higher than the mean total wealth of the poorer half of humanity. We also have the net worth of the 85 at about a trillion, or a mean of about ten billion each. So the mean total wealth of the poorer half is about $120.
That’s a median, not a mean. So it’s not precise to say that a quarter of the world could not raise $120. But that seems to be the ballpark.
What this means for negotiating our future is unclear. One thing that is very clear is that it’s very important that the wealthiest people not have badly skewed ideas about what is actually going on. From all appearances, though, they do.
