Brands do not make people feel that there is a "global village". They do not create a sense of cultural belonging or strengthen relationships between individuals. Buying things does not make you reach out or empathize with others. Advertisers frequently try to associate products to concepts such as freedom, sex, friendship but this connection is artificial and manipulative. At best, brands elicit a sense of loyalty that pushes consumers to purchase the same products over and over again out of habit. This loyalty can be highly dangerous: a lot of people get health problems because they are regular patrons of fast food chains.
In fact, most brands actually increase stress. One of the usual marketing goals is to create a need in people that didn't exist before. This can be achieved through fear, making the consumer feel inadequate or inferior if they don't own the latest items. This is especially prevalent in the fashion industry. Creating additional needs is the opposite of stress reduction.
