Final answer:
Public advertisements are considered anti-social because they promote conformity and suppress individual originality by encouraging a culture of conspicuous consumption.
Step-by-step explanation:

Such advertisements often encourage a culture of conspicuous consumption, which may run contrary to the values and interests of communities that prize egalitarianism and view public displays of wealth in poor taste.
