improved effiency only understood as "takes less labour to make widget" ... never mind the amt of water or energy or raw material or toxic byproduct involved, labour is the only 'cost' that trad capitalists recognise -- sources are infinite, sinks are infinite, all supplies are substitutable, only labour is  a target for rigorous cheeseparing...

so taken to its logical conclusion, eventually it only takes 100 people to make all the Stuff everyone needs -- but if no one else has a job, how does anyone buy the Stuff that those incredibly productive 100 employed people can make?  oh yeah, the other 8 bio of us will sell lattes to those 100 people, or shine their shoes or something :-) in the postmodern Servant Economy.
