Inequality decreases inflation because rich don't spend much of their earnings, unlike middle class and especially poor.

See: decade of QE -> no inflation; some modest amounts of cash given to the poor as covid checks -> massive inflation.

THAT is the only problem with inequality i can see: it reduces economic growth because it decreases spending in the economy. If we can somehow trick the rich into spending same proportion of their income as the middle class does (that is, simply explain them that there's nothing shameful about megayachts/private jets/private armies in the 3rd world/crazy longshot startups/islands full of hookers), things will get back in balance.
