The point I'm trying to get across is that something can be critical to a functioning system even if on its own it doesn't look very impressive. Voters are the scourge of every democracy, they push for all sorts of stupid policies and usually get them.

Literally everything? You've identified 3 product categories for products that border on scams, but literally _every_ product category advertises. I just flicked through my open tabs, and the first ad I see is for forex (www.icmarkets.com). There is no way I'd ever have heard of them without that ad; in fact thanks to this HN thread I know know how easy it is for me to get involved in forex trading :P. The 2nd is for a retail energy supplier offering me new deals. Honestly I think your 99% figure just suggests you are browsing the wrong websites. Maybe visit parts of the internet that are less sketchy.
