The global wealth distribution is predictably spiky. That’s mostly because scarcely anyone owns anything:
… it does not take that much to get into the top 1% of wealth holders. Once debts have been subtracted, a person needs only $3,650 to be among the wealthiest half of the world’s citizens. However, about $77,000 is required to be a member of the top 10% of global wealth holders and $798,000 to belong to the top 1%. So if you own a home in any major city in the rich North on your own and without a mortgage, you are part of the top 1%.
This looks like what you’d expect if population — at the global level — expanded approximately to the resource limit. (There are no doubt cuddlier interpretations out there.)
