the post acknowledges that the numerical value difference will decrease, while also acknowledging that the reality is barely different at all. so if you really want to say "the distance between wealth is less unequal" then, congratulations?
if you looked at "wealth inequality" at the very bottom of an asset crunch or recession, and never even saw what it was at the top of an asset expansion, you would still say "wow wealth inequality is super wide" only to be flabbergasted or amused at how much wider it gets
so its kind of a useless distinction if the realities are so widely different either way.
