A BMW/Mercedes might be a more quality car than a Kia but someone that only has a budget for a Kia isn't going to even consider a BMW/Mercedes for 2x to 8x more.
On top of that "quality" is subjective. I might agree that a Macbook Air ($999) is better than a $300 window laptop (there's tons of them) but both the Kia and the $300 Windows laptop will serve people's needs. a Kia will get them to/from work. Let them transport their kids. Etc.. A window laptop will let them browse the net, view youtube, write a resume. It's not like the Kia and windows laptop are useless. Plus, for the laptop, they can get 3 of them for the price of 1 mac. So everyone in the family gets one. It's like buying a Vizio TV for every room instead of one Sony TV for one room.
Right, we agree then. People do care about quality. That was my point.
I made an example to explain what would happen if consumers had a way to know, for sure, the quality of a product.
I didn't mean for you to take my example, try to find smartphone models that may match and then come back to me saying "your example is wrong because I can't find those models in real life". The whole point of my example was to share an idea, not to sell a smartphone.
