Good grief. Any child with $2 in pocket money has more wealth than 2bn people. If you are a doctor with a massive student loan, you're probably in the bottom 10% of humanity in terms of wealth.

Yet killing these 8 billionaires and taking their wealth would do almost nothing when spread across the bottom 50% you are comparing them to.

You don't raise civilization by chopping off the top.

Which is itself a rigged stat.
