You're using the negative connotation of efficiency that should really be discarded. It doesn't only mean "more, faster, because higher profits, work like crazy until you die", that notion is extremely narrow for what efficiency actually means. Efficiency saves lives right now. It is also what will enable us to save our species from the destruction of the planet. In a world as populated as ours, efficiency is by and large what the very concept of sustainability itself consists of.
