Actually you could judge how much you value the rewards and dislike the work to determine the most valuable way of life and choose your career accordingly. Male porn stars earn less than stock brokers and brokers are probably trhe hardest workest in society. This is because no one wants to work as a stock broker and everyone wants to be a porn star, thus pornography companies don't have to pay much to get a male porn star, not much at all, whilst groups like NASDAQ have to fork out 6 figure incomes to gain the limited supply of stock brokers.
You will also find that people enjoy cleaning and labouring since it doesn't require much education. They are prepared to be paid less.
