Why do men envy women? it's not that grass is greener on the other side?

I mean.. let's say you were born as a woman. what if you are fat, ugly, deformed? I mean... you think you can become a star using your body shape and beauty but what if you are born as ugly woman? Do you still envy her life? I mean.. are they really serious that they can sell sex as a woman and live it up? not all women are living up to the dream. the women that they see is like 1% of all women. ugh.. men are so stupid. it's like a woman envy a man who born as a son of billionaire
