Many assumptions the TRP community makes rely on economics - but surprisingly, that is not the case when it comes to value.

Mostly they just state some supply/demand stuff, but that would only explain pricing based on some sort of currencies like sex (or KPIs as in X/10). Or sometimes they refer to some somehow universalistic values like age, fitness, ability to breed, number or sex partners or whatever that make up for these KPIs.
