I think that greed is easier to manage when expanding into underserved & undercapitalized markets - in that environment most capital increase becomes an easily spread general improvement in life quality.

When trying to balance inequality in well-capitalized, mature markets, you fundamentally have to trade one set of ownership against another on a much more frequent basis. To replace one set of capital investments with another (even when the new investments are an improvement), requires displacement of the old owners and old industry; see fossil fuels and climate crisis as a major example. Government becomes a battleground between the capital interests and is often where progress is neutralized.
