Why do you expect to be reward for being a good person? That’s just the baseline everyone should meet.
You will never get financially ahead of everyone else by being a good worker bee. Sorry your parents and teachers lied to you. Doing well in school and getting a degree is not a pathway to riches. The vast majority of people who went from rags to riches went off the beaten path and took a massive risk.
Also sex work doesn’t make someone a bad person.
There are even niches within foot fetish porn. Like people with a fetish often have a very specific kind of fetish. Foot fetishists aren’t just into feet but for example also want to see the feet in specific color nylon socks or have a humiliation fetish. And most of the niches are probably underserved.
