It's a win-win situation. With intelligence, you have the power to change your world and be a strong, independent person that contributes to society.
With beauty, you are a god walking among humans, and if you're a beautiful female, you can choose to never work a day in your life and be pampered by thirsty old moneybags and reach the same quality of life as the intellect.
If you have neither intelligence nor beauty, welp I guess you better work bitch.
If I were the most beautiful girl ever, I could probably get an old rich guy to marry me and never have to work. However, I like to be able to take care of myself if need be and beauty fades, what will you do when you're middle aged, botox makes you look scary and emotionless. Also I hate when people look down on me, I like being respected
