Justifying an 'Unjustifiable' Profession

Left-wing economists, ever eager to snatch the scourge from the hand of God, hold that advertising tempts people to squander money on things they don't need. Who are these élitists to decide what you need? Do you need a dishwasher? Do you need a deodorant? Do you need a trip to Rome?

I feel no qualms of conscience about persuading you that you do.

What the Calvinistic dons don't seem to know is that buying things can be one of life's more innocent pleasures, whether you need them or not.

- David Ogilvy, Ogilvy on Advertising.
