Seems I am catching a bit of flak on this topic, which is OK, and to be expected, so I thought I would express my thoughts a bit more fully.
I like Wal-Mart. I spend a lot of my money there. So this thread is not a knock on Wal-Mart.
What I don't like is a manufacturer losing their focus. There are many companies that start out as a family owned business and eventually become a public corporation, with shares of stock, a board of directers, etc. Often, the person who started the company sells the company, or is forcibly booted out if he/she is no longer majority shareholder. In effect, it is no longer their company.
The drive for corporate profits then leads the company to seek ways to generate ever greater profits. That is the nature of corporations and the Wall Street mentality. Often, products lose quality in ways they hope consumers do not notice. New products are introduced to reach new market segments. This activity takes away the focus on producing the best quality product possible, and turns into building a product to a price point.
Small companies not controlled by a stock price, but rather by people who love what they are doing always make the best products. For example, BMW is one of the most respected automakers in the world, and they are family owned.
I feel Zeiss is on the path of being corporate profit driven. One merely has to look at the first generation of Victory binoculars to see how they lost their way. The other new series are a degradation of their original products to compete with more market segments.
Some will state that having the lower end products helps a company stay in operation, and therefore continue to produce the top quality products. I believe that having lower end products distracts the company and clouds the mind of the consumer as to just what does this company stand for. The end result is a battered image, and a loss of what was succesful for the company to begin with.
