Wealth Distribution and the Yard-sale Model
How do we, as a society, end up with a tiny handful of ultra-rich individuals while the rest live in poverty? Better yet, why do societies allow this to happen? Mathematicians have something called the Yard-sale model that explains why.
This is the crux of the Yard-sale model. In a free market, one person ends up with all of the wealth – completely by chance.
Spoiler, the solution to this problem is wealth redistribution.
