Great phrase, why isn’t it used?

This show from Canadian TV features a carousel scheme designed to evade taxes by passing purchases around a circle of temporary fake companies. The purchases in this case were packets of “telecom minutes”.

Carousel scheme is a wonderfully descriptive phrase but for some reason it hasn’t spread. Google leads only to this specific scheme, not to the hundreds of other examples. The BIGGEST carousel scheme right now is the circle of AI software and investors and chipmakers. Nvidia, OpenAI, Microsoft, and a dozen others, all passing “growth” around the carousel.
