I agree. Both the simulation and the analysis are quite useless for two reasons.
1) It doesn't perform any analysis of the individual population members between time-steps. A members of the population jumps randomly within the income distribution after a transaction and the plots don't account for this. I would like to see the average wealth of each of the population members over time. I'm guessing it will be 100.
2) The transaction function is entirely unrealistic causing and making addressing 1) pointless since each population member is essentially a new born between time steps.
That said, it an interesting exercise in how one can generate a beta-like distribution.
Overall, this is too far removed from reality to be of use in debating how to address income inequality.
