Interesting perception and good arguments there. I like it.

Maybe, in the next post you can take the analogy even further:

• why a merchant uses a low price on goods that are sold in large volumes
• why he arranges the merchandise to catch the most of the client's attention.
• why large volumes with low profitability are better in the long run for most of the merchants
• why the client should always be pleasantly surprised
• why a clean / ergonomic / good smelling / good looking shop is better even if it sells more expensive.
• why the responsiveness is crucial.
  ...etc

What do you think ? Can be an interesting sequel ?

Fine post. :)
