Scarcer? Probably right. More efficient? That seems very, very wrong. We're constantly looking for more efficient ways of doing and building things - if you'd like to frame this in a cynical way, look at it like this: businesses/industries are always looking to reduce costs. Sometimes this is done by firing thousands of people, sometimes this is by using more efficient materials/processes.
