I remember a book from a number of years ago, called Jennifer Government: https://en.m.wikipedia.org/wiki/Jennifer_Government which suggested companies ran the world, and were divided into two customer loyalty program-based alliances. Everyone essentially belonged to one camp or the other, and it's surrounding ecosystem. It's hard not to feel that as an example of today, where people live in either the Apple or Google ecosystems, and only use products or services that integrate with that ecosystem.
