I modified the simulation as follows: I allowed it to evolve for a single generation, enough time for the top 20% of the population to have 80% of the wealth.

I modified the simulation as follows: I allowed it to evolve for a single generation, enough time for the top 20% of the population to have 80% of the wealth. I now choose a random sample from the top 20% of the population to follow, lets call them T20. I now repeatedly 1) pass the wealth of all actors to actors with new, random abilities 2) let the new actors compete for a generation (the same number of competitions we used above) Result: After 3 generations of steps 1 and 2 above, 80% of T20 has lost almost all their wealth, 10% has lost 75% of their wealth, 10% has done really well, growing it by a factor of 8, due to capable ancestors for three generations. Amazing, it matches the statistics in https://www.theglobeandmail.com/globe-investor/globe-wealth/eroding-family-fortunes-how-the-cycle-can-be-broken/article33757468/ https://www.theglobeandmail.com/globe-investor/globe-wealth/...
