There is another good and free article from Fast Company. It reflects on an interesting thought - are we really running out of scarcity? I think not, but the author has some good points:

"Scarcity, after all, is the cornerstone of our economy. The only way to make a profit is by trading in something that's scarce. This is why the music and movie industries are so terrified by the millions of people who download entertainment from the Internet every day. Downloading threatens to make supply virtually unlimited, and that could make their offerings about as valuable as those of some kids down my street who recently tried to run a stand selling freshly made mud."
