We have control over how society's feedback mechanisms are structured
We do. However, that doesn't mean that tweaking knobs won't simply result in a pareto distribution with different winners and losers. At the end of the day, every individual has fitness along a variety of different vectors. You might achieve equality along one or two vectors by tweaking one knob, but then see side effects that result in pareto distributions along different vectors.Income distribution is a textbook wicked problem: https://en.wikipedia.org/wiki/Wicked_problem
My view is that income equality is the wrong thing to optimize for. Instead, we should optimize for progress and productivity that increases the overall welfare of society fastest, even if some individuals do far better than others. Those individuals capable of contributing the most to meeting the needs and desires of the most individuals deserve the most resources to enable them. Those who have the least to contribute will benefit via surpluses created as a result of productivity gains.
