The thing is business is more booming than it's ever been, but making the line go up forever is a fool's errand, at some point you'll hit a peak. Hitting that peak is immensely punished in our economic system.
If you make a hammer that'll last 100 years, you'll sell as many as you can reach customers who need one, before hammer sales plummet. Instead of being rewarded for making a great product, you'll be punished when sales fall because you've solved a problem for most people.
Advertising is kind of neutral in abstract in my head. Make a great product for a fair price, and let people know about it, and that's actually probably a benefit to both parties. Make a terrible product, and tell a bunch of people it's great, and you've spent resources doing them a disservice. But if you can convince them it's good enough to spend money on it, and keep your revenue per customer above the cost to acquire them, it's profitable. And that's all they care about. It's basically the same pattern as a scam, but profit is the only thing they're told they're allowed to care about.
Would it have actually worked though? The access Hollywood tapes came out during that election, Trump's behavior of entering the dressing rooms of Miss Teen USA were well reported on, and neither really hurt him. Maybe there's a chance it would've changed the outcome, but it's hard to imagine that chance is large.
