Much as we'd like that to be true ideally, does it happen (in terms of inequality reducing)? I see no evidence of that, it ebbs and flows in various time periods and civilizations. One can try to resist that reversion to the mean but they'd historically be proven wrong.

For a start by not tearing down the systems that kept inequality in check in the past. Like union membership or banking regulation etc. just to name some examples.

The tearing down of those institutions IS the ebb.

That's like accepting burnt coffee is the average, so why try to make a good tasting cup. Nonsense.
