Isn't this what you would expect? Advertising fundamentally is trying to convince you that you need something. If you're perfectly happy with your current situation then what else would you need? So the advertising has to convince you that you're not happy but that there is a product that you can buy that will increase your happiness. You're basically being negged by advertisers.
I would go further and state that our entire economy and society are based on the manufacturing of demand. There are so few things we actually need. Food, water, clothing, shelter. Everything else is a luxury you've been convinced to buy (or it was given to you by someone who was convinced). I'm not talking about ethics here, just straight facts.
