There is clearly some benefit to cumulative returns of the sort measured in this study. Signaling that leads to "the rich getting richer" reduces friction and transaction costs, allows resources (capital, attention) to be allocated to those who can most profitably use it. So to some extent we would want the rich to get richer. But there is some point where snowballing success becomes counterproductive and enables rent seeking laziness.
