Didn't you just prove their point / agree with your post? The German car pricing example fits right in the "people can't judge quality adequately and marketing does the rest" narrative:
People buy overpriced cars that are not actually high quality.
or
You/marketing are telling me about how these chinese cars are higher quality and I should by them. While most people have no Idea whether "green engines" are good or bad. I could take your word for it and believe that they are inefficient. But that sounds bogus given that efficiency is a cornerstone of "green".
I'd like to see this backed by data. I believe the anonymity of the platform helps remove a lot of the stress, bullying etc. that make instagram so toxic for teens. There is shit content on both platforms. But no one at school associates your social standing with your reddit account karma.
