I was just about to post the same thing, but thought to check someone hadn't achieved frost piss. ;-)
I think it need elucidating to some though: Pareto said something along the lines that 80% of his garden peas came from 20% of the pods. Juran noticed 80% of the wealth was owned by 20% of the population.
Now, you can extend that: of that 20% likewise 20% of those people hold 80% of that wealth too, and similarly in that group too 20% holds 80% of the wealth. Now you reach a limit as humans are countable.
i.e. it's a simple power law distribution applied to integers.
So, when you read 85 people own 50% of the world's wealth it is nothing more than fun with statistics time.
