Why the super rich are inevitable

Why some mathematicians argue the economy is designed to create a few super rich people – unless we stop it.

@anirvan I haven’t loved a site this much in a long time! Wow.

Ah yes, the oligarchy game. I made a prog to play that, complete with snark, and the ability to redistribute a portion of all players’ wealth evenly.

It's not bad. Just I keep winning in the coin flip game

@guysoft @anirvan
See? The game is not rigged, you all just have been playing it wrong...

-The rich guys, probably.

@anirvan it's so cool. Thanks. I would say even after redistribution model, the curve is exponential. So the question is how big should be the base of this exponential curve to feel like a good society. With this article I see the problem, but the model that looks like what author suggests is worse, IMHO.
@anirvan @hadilq Btw author didn't mention this is happening because everyone only can risk %20. Actually I can think of better models. What if we fill the risk gap, instead of completely redistributing money.
