I get what you’re saying, but it really comes down to just addressing the problem directly.

Homelessness crisis -> provide housing for all -> not enough supply? build more -> can’t build because of zoning? fix the zoning -> etc

It’s the same thing with wealth inequality. Tax him until his wealth isn’t that unequal. If you then decide that the CEO of facebook has too much power you can break up Facebook, but that’s a separate issue.
