I think the real issue is that we are emotional beings and wish to feel loved, respected, appreciated and wanted. The world has been turned in to a very cruel place and all are suffering inside due to these lacks or lack of fulfillment.
People try to change their looks just in case that helps them. Plastic surgery, make up etc etc is all part of same issue. Others simply exploit that to their advantage.
The real peace of mind can only come from idea of caring for each other and sharing with each other our world. We need to become realistic so that we could create the real world for ourselves. The skewed world views is not good for anyone in the long term.
