I can’t actually answer why they don’t set a hard limit of how much they will let some one accumulate or as for why they didn’t use coops. Both of these are counterfactuals that would be difficult even if I knew all the internal discussions. For example, you’d have to look closely at Deng’s policies and the subsequent three represents during the early 2000s to see what the discussion around coops was. Hard to say what the thinking was that precluded coops from the discussion.

It’s easier to say what they are doing and the policies they are enacting. I believe they have a goal of reducing inequality with a goal of a Gini index of .35 by 2035. They are focusing on a common prosperity goal. This has led to increased donations and contributions from the wealthy to social causes. With the common prosperity project, they hope to increase the middle class and reduce the rural-urban divide as well. I think there are several other goals.

I don’t see setting a hard limit on whether or not one is a billionaire contributing to these goals and then runs the risk of creating resentment of a particular class that the party needs to grow their level of prosperity.
