Buying happiness

I feel that Maslow and Aristotle's idea are very similar. "The central issue for Aristotle is the question of character or personality — what does it take for an individual human being to be a good person?" and similarly, Maslow's self-actualization need (which is the highest level a person can reach) is "the instinctual need of humans to make the most of their abilities and to strive to be the best they can. Working toward fulfilling our potential, toward becoming all that we are capable of becoming." To be a good person and strive to be the best one can are one in the same.
I don't believe that a person can become their best self simply by buying a certain product. If this were so, we would all be wonderful people and we'd be sitting around the classroom in our Nike's, singing Kume-by-ya and attaining spiritual enlightenment. It just doesn't work that way. The clothes do not make the man!!! It's what's inside that counts and that is where spiritual enlightenment or self-actualization must take place.
I don't think that it's necessarily wrong/unethical to try to sell a product by appealing to a persons deep desire for actual happiness. I think most advertising does this on some level. whether it be a Zale's diamond commercial or Nivea body lotion, most commercials tap into the consumers need for happiness and try to associate their product with finding such happiness.
