I agree that's a difference, I simply don't agree with your original hypothesis. The constant hunger for more and more worldly things isn't going to go away, or even get significantly better, if we erase advertising and social media from the world.
I'm of the firm opinion that advertising is snake oil. But even if you do believe that advertising causes demand, it doesn't follow that we would see a significant decrease in demand if advertising was gone. If advertising hypothetically increases demand by 5%, that's not going to make that much of a difference when it's gone.
