I'd go further and say that branding is now often the product itself.
Nike can sell a hat for 20X more than a generic hat when it has their swoosh on it. Perfume is basically a generic chemical wrapped in a huge amount of marketing. Apple makes excellent products, but there's no question that at least part of the premium you pay is not for better quality, but for the brand itself.
While the value of a brand often revolves around vanity and advertising, there are often other factors that are also not directly linked to product quality: such as "fair trade" coffee, buy-one-donate-one shoes, or humanely raised animals for food.
We're moving from a pure "consumer society" into something a bit different (but definitely still consumption based), where consumption is not just for the direct benefit of the consumer, but is also used to signal deeply held values.
