do wealthy white men generally prefer slim women, or is that a stereotype?

i am a 23 year old fat biracial woman (black and white), and i came across this facebook post:

“I’m going to take it further and say: Black men love big fat asses because they know white men do not. They don’t want the most powerful men as competition. White men stray away from big fat asses, because they know black men love it. They don’t want to be associated with what black men desire. Black men stray away from the uppity, petite, slim girlies that will attract men of other races due to insecurities.

‘I need my girl with meat on her’ na…you want less competition.

Slim, uppity, attractive women have the world in their hands. Men are aware of this.”

this post honestly got in my head more than i want to admit, and it made me think about beauty standards, race, and desirability in a very uncomfortable way.

i am not looking for comfort or reassurance. i want blunt honesty, even if it is not what i want to hear.

is there any actual evidence that affluent white men generally prefer slim, petite women more than other groups do, or is this just an internet theory built on assumptions about attraction and status?

i would especially like answers from people who have experience in affluent social circles, nightlife, luxury industries, country clubs, or anyone familiar with research on attraction and dating preferences.
