I get the humor here, but let me be blunt. In my field (healthcare), I would never tell a client: “I believe you should pay me more, just because I feel undervalued.” That would be absurd. I provide a service, the fee is set, and people choose to accept or not. If the pay isn’t enough, you either improve your offering, negotiate within the system, or change profession.
Games, art, music—these are optional luxuries. Nobody asked for a game to exist, and nobody owes extra just because the creator feels underpaid. If someone enjoys a work and chooses to give more, that’s fine, but it shouldn’t be presented as if the audience has a duty to support beyond the price tag. A “reverse sale” is funny as a joke, but when it crosses into entitlement, it risks alienating the very people you want to reach. In the end, value isn’t declared—it’s earned, and people show it by choosing to buy (or not).
