No. Yet, if you're cynical enough everything is a pyramid scheme. And, then maybe you're able to see that the economic systems themselves are full on that unsustainable growth (if, for example, you start looking into how the 'natural resources' are exploited to be centralized in important cities/ countries yet the environmental costs are never paid by the latter and so on...)

Nothing like pyramid scheme because what sustain the “scheme” overall is public interest, generate experiences that people pay money for and companies are willing to sponsor. It’s not the new young players that input all the money in the industry.

Even in the case of very young players that are paying to play, it’s the parents money, so not exactly “youthful optimism” that powers it.
