Critiques of class structure
Various critiques of the class structure tend to focus on contractual class, and is also generally made by those with a low general class who are under contract, but whose contracts paint them as the villains or make their life worse.
Critique is mostly levied by them due to the fact that they generally have little to no agency over their lives, and are also ostracized due to their contractual roles. Most royals at least get the popularity that comes with their roles (see: contract-based celebrity), but the villains of unpopular stories are consistently disliked.
However, the majority of the population is not under contract and views the contract system as good and just, so dissenters are often not heard, especially in the case of villains who are already not trusted.
