Apart of encouraging crime this ever present propaganda has other adverse consequences. A common human trait seems to be an insatiable yearning for more. Advertisement tries to encourage this trait without ever satisfying the yearning. This might be a major reason for our current very energy and resource intensive lifestyle. This lifestyle has to change in order to safe at least a bit of our biosphere. (hush, sub prime crises is intentionally not mentioned here).
Advertisement is a large scale deployment of disinformation. Disinformation should be regarded the archenemy of information society because it strongly decreases the efficiency of such societies. Indeed advertisement seems to not provide any common value (apart from being a money dispenser for creative projects). Thus all labor invested in this market sector is wasted when considering the whole national economy. It is a very harmful waste of resources.
