I agree with you that it is better to give one’s money to worthy causes. But it could be that someone needs to wear brand names in order to feel respectable in their social group.
But there are also people who just want to be the most stylish of their group. Some people need that, but for some people, it is a waste of money. Is that what you are talking about?
