Then let’s control for that. Among people with a decent safety net, can we correlate eventual success with number of tries?

The answer seems self evident, but idk for sure, and I would like to know the Gini coefficient of successes vs failures among safety netters be that of non-safety netters. Wouldn’t we expect the successes within the safety net to be massively larger on average than those of the non-safety netters, given that a safety net affords you so many more swings to take? Your comment suggests that this is not the case, driven by the selection/survivor effect within non-safety net
