Ahh..well, Q, that (inevitable changes) may be so...but there are other things that 'may' be judged inevitable that we do not appreciate.

Such as rampant illegal immigration, overfishing, nuclear proliferation, etc.... (make YOUR own list)

There are a whole host of business practices that may be legal & profitable, but not terribly moral & fair. Walmart takes some of these further than Sears or Penny's ever did. Does that make them just 'smart' because they skirt illegality closer than most?
