Economic consumption literature help

I am looking for literature about the term "economic consumption", or rather, the term that describes the macroeconomic process of promoting the contraction of the agriculture industry in favor of higher paying manufacturing jobs. I learned about it on this site and on some farm's website but they are all escaping me, perhaps because I am remembering the term wrong. I know Alan Greenspan has used the term in question and that it is a real term, whatever it is.

Thank you!

it was creative destruction. nevermind.
