This is a pretty wide open topic. You might want to narrow it some. One angle is to consider the concept of beauty in the last 100 years has been increasingly fuelled by commerce (in western society) The unattainable, especially for women, causes them to buy more to achieve the illusion. Make-up, weight-loss products and plastic surgery is a multi-billion dollar industry. Thus "beauty" has become a commodity, an illusive commodity designed to make people feel "insecure" through fashion magazines, shows....Hope this gives you an idea to go on.
