This is an excellent analysis. It's also why I stopped considering a brand as an indicator of quality (in either direction) a long time ago. That something is a recognizable brand doesn't really mean much.
Or you just have enough money to buy only from less-widely-known but actually-good brands and don't worry much about price. The ones that haven't started cashing in on their "high class" branding by moving down-market toward the middle class... yet.
