It's a simple analogy that applies to the bags. Check this out:
I like soup. Tomato soup, in fact Campbell's Tomato Soup. It's the greatest tomato soup ever made. It's best with a sandwich or a salad, it has an even consistency and a rich flavor. It cooks well with a bit of stirring and an eye on the heat. It's also more expensive than the store brands that are merchandised next to it.
Okay, so I decide one day to try the store brand (I've tried several) because it's less expensive and perhaps some consumer reporter on a local news station says it's produced at the same cannery that produces "high quality, name brand soup". Now I'm skeptical, so I only buy one so I can try it out.
Cut to the chase: The soup is terrible. It tastes like pimentos and chalk. It cooks like pudding, and my lunch becomes an ordeal. So, what do I do? I never buy it again, and I go back to my beloved Campbell's Tomato Soup. Why? Simple: It's a better soup, and it's worth what I pay for it.
So, if individual consumers are selective and are willing to experiment first before commiting to products, you would think that corporations would use the same method to judge products they use on aircraft. It shouldn't be reserved for seats and desserts. It should apply to garbage bags, toilet tissue, pretzels, carpets, et al.
High Quality and Low Cost do not have to be diametrically opposed. There is a happy medium where both cross. It's Economics 101, folks.
