I have to disagree with you there. If Mcdonalds had such an "awful" product, nobody would eat there and it wouldn't be as popular. There are plenty of alternatives.
The point I was trying to make with the McDonalds example was simply that a scalable and successful business model necessarily implies that they are unable to create the "perfect" hamburger. They have practical limitations inherent to their process that makes it impossible. If they instead were running a two star luxury restaurant they might have a chance at making a perfect product. But that wouldn't be a scalable and sustainable business, and most like not very profitable either. Most luxury restaurants have extremely low margins and in many cases operates with considerable losses.
And just to make it clear, I am not trying to criticizes capitalism per se. I'm only basically stating the same thing the article is stating; that there is an inherent paradox in capitalism that makes it more complex to deal with than is directly apparent. Everyone that goes into business or deals with business indirectly through policy-making should be as aware as possible of this paradox, simply because it will prevent us from collectively ending up in a world with great processes but awful products or with great products but awful processes. Neither of which are very tempting scenarios.
I was going to reply with what you said but then I thought, since they're the in that "most calories per dollar" bucket, maybe poor people eat there out of necessity and not choice...
