> I'd frame it as "How resource-producing capital promotes inequality". It could be livestock in a migratory herding society, or boats and nets when those were critical for fishing, or whatever.

I agree, but nitpick: capital by definition can be put to use to produce or gather something. So resource-producing capital is redundant.

Yes-ish? I'm not a CPA or MBA (ditto most folks here) but looked at a few online dictionaries for "capital". From cases like gold in a hunter-gatherer society - a status-signaling luxury and trade good, but you probably can't get much more than perishable foods or nicer stone tools in exchange - it seemed worth the clarifying/emphasizing redundancy.
