Prettyness isn't some incredibly rare resource in a healthy society.Because they are pretty and subservient and the fertile women are in a tiny minority.
Its a status symbol to get to rape one who can have children and impregnate her. Not every one is high class enough to obtain a fertile wife or indeed "hand-maiden" (the rape object).
Read. The Book.
It is quite common when girls take pride in their appearance and try not to get fat. Look at old photographs from decades gone by, most girls were pretty and had good bodies.
Status amongst men is largely about showing it to impress women. We don't use women to obtain it. We use status to obtain women.
Directly transposing female motivations on to men reminds me of low rent sci fi where men who have never had sex with or been in a relationship with a woman write male characters with male motivations into female bodies.
