You have it entirely backwards. The advertisers on things like facebook should be paying the users for using the site and getting their ads in front of them. facebook is not even worth $1 a month to most people, that's why the won't charge for it, and shows it's actual value to the end user. The real benefit of facebook is to the companies trying to shill their wares on facebook.
