The solution is to not buy anything which is advertised, sold through cold-calling. We could learn something from developing countries and some developed countries. They have open markets where people go to buy stuff. Humans have been doing this for thousands of years. You can haggle with the vendors and examine the products for sale. In the US, these open markets in a city center do not exist (Maybe except for swap meets and farmers markets) Would it be possible to do this on the Internet and cut through the vested interests? Instead of advertising, when one needs a product or service, he visits a large scale virtual open market/bazaar where he can talk in real time with the vendors see videos of the product, and haggle on price. To me, advertising is mostly pushing products which people want and do not need. Advertising is expensive. If most people didn't respond to advertising, the things available for sale would be of better quality and at a lower price.
