Glad to be of use! It’s a pretty nuanced area of English, so I can understand how being a non-native speaker would make it even more difficult.

I think the reason they decided on the tree lean/fruit quantity was to try to contrast inequality stemming from historical reasons with inequality stemming from no assistance being provided in that moment. Actively withholding needed resources can have the same effect as a system providing unequal resources over time, even if the historical reasons for that inequality weren’t decisions anybody alive today is responsible for.
