This has very little value to me. I'm buying my wife a new car next year and I won't be perusing adverts to find what to buy. If I did I would be thoroughly mislead as the adverts are full of aspirational bullshit.

Adverts encourage people to eat unhealthy food, take unneeded drugs, drink, smoke, buy more house than they need and replace perfectly functional consumer goods. They make everybody's life worse (apart from the advertisers).

Commerce won't stop without them. I've mostly eliminated them from my life but that hasn't stopped me from spending my money.
