What's a logo worth?

Have you noticed that every single car made has a logo on it? Jeans, too. Not business shoes, but computers, certainly. Phones. Not ties, except maybe Hermes. Not most jewelry, either.

It's funny. We probably wouldn't take $50 or $100 to plaster a logo on the back of our business suit, but we pay extra for a logo on a TV set.

Pencils, yes. Very few foods, except maybe Oreos. Watches, certainly. But not most of the furniture in your living room (though if anyone could do it, it would be Barbara Barry).

Is a logoless car worth more or less than the typical kind? Why do we not only put up with it, but expect it and like it?

Apparently, it's not just a pencil, it's a lifestyle.
