They should have used the term more valuable not more wealthy, their point is generally cogent.

On the wealthy side, you don't need to be that rich to pay not to get ads.

Fair enough, but keep in mind that many Americans are just not wealthy enough for a lot of advertised products; a luxury car ad, for example, is mostly useless if it's shown to people making < $60k a year.

This demographic is inherently attractive simply because they can spend money.
