Isn't a lot of that older than Amazon? Walmart was already hard to compete against for family-owned retail businesses. Three Walton heirs are in the top 15 richest Americans, if you want to talk about distribution of wealth. To me Amazon seems like just the natural next generation of the Walmart model.
- distribution of ownership of the 'means of retail production'
- worker rights (looking at you, gig economy and Amazon delivery drivers)
- brand reliability (so much on Amazon is brand-free)
