No, there's plenty of money in alternative careers to advertising. It's absurd to claim otherwise.
But advertising is an easy way to make money fast, that is, if you're happy to sell people stuff they don't need at triple the commodity price. Or... you could turn your hand toward more constructive and lasting alternative endeavors like treating / defeating disease, cheaply desalinating sea water, or a zillion other ends that would do more than pry money out of the clueless hands of fools.
