If you have $1, you have to give it away, but you receive less than $1 back on average (because some people have no money to give you). So the poor get poorer. But wait, by the same argument the rich get poorer and this simulates a system of stochastic handouts to the very poorest - those with $0.
Alternatively, it simulates a lottery. From the point of view of any individual, every turn you spend $1 on a lottery ticket and get a prize of between 0 and $99. Viewed that way, it's not surprising that some people end up rich in the simulation.
