Why don; stores will not sell solid wood flooring in California?

I understand that plywood must pass from solid wood, but all retailers try to talk to me Out of It! Most houses here are built on concrete, and they sell solid wood, then what is the problem? This is really starting to bother me that technology can be so expensive!

You do not want you to sell because they sell more to gain if they cheap crap. Let not make you change your mind.
