 The persuasive component of advertising is also a fruitful subject of ethical inquiry. Galbraith (1958), an early critic, thinks that advertising, in general, does not inform people how to acquire what they want, but instead gives them new wants. He calls this the “dependence effect”: our desires depend on what is produced, not vice versa. Moreover, since we are inundated with advertising for consumer goods, we want too many of those goods and not enough public goods. Hayek (1961) rejects this claim, arguing that few if any of our desires are independent of our environment, and that anyway, desires produced in us through advertising are no less significant than desires produced in us in other ways.
