I watched an interesting documentary about the growing modeling school industry in Siberia, where parents sent their daughters to learn how to walk, use body language, use makeup and attractive hairstyles, and dress sexy, with the main objectives to become high paid models (mostly in Asia), and/or to land a wealthy husband in the West.  The Russians are realists.  

Here in America, why do women shave their legs and armpits (and other places), wear high-heal shoes, short hemlines, and show cleavage, if not to look sexually attractive to attract a better class of men?  It's Mother Nature's way of improving the gene pool.  Capitalism through sexuality.
