Well, welcome to all of life. More attractive people, taller men etc. get hired, promoted and trusted more. Not just in porn, not just in regular modeling or acting or singing, but also in any job. They get better options in the dating market.
Genetically more intelligent people have higher chances at high earning jobs.
The pattern on cashing on genetics is extremely widespread and it's also not entirely clear it can be abolished without screwing up society. We do need the right people for the right jobs. You don't want to watch ugly people's porn (except if that's your thing, no kink shaming implied!), or marry stupid people etc. etc. You may try to console yourself that individual hard work can override all that, and it can to a degree, but we like to kindle ourselves in the fairytale of the "just world fallacy". Reality is harsher.
Genetically being superior today is essentially a lottery, while then, it would be something you can buy. Imagine that society.
But what if some people become fundamentally better, an actually clearly superior "race", ie the Nazi myths of superiority becoming fact (as applied to this new optimized race/new entity)?
Society isn't prepared to talk about it.
As someone who is a supporter of legal sex work and pornography. The "cashing on genetics" part bothers me the most. I don't know how to process when good looking people can earn thousands of dollars almost doing nothing (particularly on digital platform like OnlyFans), whereas regular people have to work day and night to earn a living. Right now, when sex-work is stigmatized, it seems fair because they are getting paid a lot while suffering the stigma. Similar to a lot high-risk job is also high paying because of the high risk. But once sex work gets accepted in the society, then why should they get paid so much without the work like rest of the society. Maybe if sex-work gets destigmatized it will not be very high paying profession.
