If you have only beauty, you're stuck needing someone to take care of you. You might be able to make some money as a stripper or a model for a while, but once you're past your early 30's that's pretty much over. Unless you have some brains, like say...Cindy Crawford, you won't be able to be financially independent because you haven't planned for the future.
If you have brains, and aren't beautiful, then well...who cares? You're independent and too smart to care that people aren't drooling over you.
