To me this is simply a consequence of the capitalist mode of production.
That may be true but I think the unspoken assumption in your comment is that somehow, without capitalism, greed magically melts away. How do you explain the constant extreme rampant corruption in communist and socialist countries over 100 years if not from GREED?
Capitalism or consumerism, a never ending offer and demand for goods, material or immaterial?
Yes, because governments are so restrained in their use of propaganda.
What it is is the consequence of the power existing. 200 years ago nobody was arguing about how to hook people in the first 0.2 seconds of video, but it's not because nobody would have refused the power it represents if offered. They just couldn't have it. It's humans. People want this power over you. All of them.
