They would not sell (nor profit) something that people refuse to buy.
So they are wasting money on hiring advertising and marketing companies?
Then there's also planned obsolescence and licensing deals that make it impossible to continue using and repairing things (even mechanical things like tractors, and living organisms like crop seeds).
Sure, people can try their best, but there is only so far we can go before it gets so inconvenient to not fall into the consumerism trap.

I dropped my niece off at her elementary school the other day. Being newer to the process I parked the car instead of the whole drive thru setup they have in the USA. I saw all the huge SUVs and trucks and I knew I had to walk with her the mere 25 ft (7m?) because they would not see her. Sure enough, one of them was about to take off and braked hard when they realized I was there, but my niece got scared. I'm sure the driver never knew she was even there.
