Trade

every trade is fair. watch what happens anyway.

equal starts, fair coin-flip trades — one person ends up with everything

Every trade is a fair coin flip between equal parties, each staking a fair share of what they have. Run enough of them and wealth still concentrates toward one person holding it all, unless a small constant tax gives back what it takes.

Concepts: probability, inequality.
