I'm not sure that's necessarily true. On the web, it's often the less savvy users that convert best in response to advertising. For example, a lot of money is made online selling payday loans, ringtone-related subscription-billing junk, and 'magic' tooth-whitening and weight-loss formulas. Ignorant, poor people are often the most easily monetized, and I'm guessing they're often the least likely to value their time enough to pay $15 to avoid ads.

I'm not saying you're wrong, but I don't think it's as straightforward as you indicated.
