I think the point is that this only works in the aggregate. Individuals in a group/organization/society can make small positive decisions that improve the likelihood that any individual in that same group will get "lucky".

There's a sort of "freeloader" problem, though, which is that the ones who get "lucky" don't themselves have to be making positive choices. In fact, being a selfish individual in a group of generous ones can be an easy way to get ahead - as long as you can get away with it without being noticed or punished.

The point is not that individual luck plays no part. It's about what your environment offers you as a baseline, not accounting for individual luck.

I don’t disagree but there is also an immense impact of random, pure luck outside of any environment that plays a huge part in many lives
