Directed Culture Change

I am hoping to find a better text than this, Culture and Change: An Introduction.  What ever the case, the text will likely have to answer to the basics presented here.

I was immediately concerned about the ethnocentrism of the author when it was stated, "Because people are always looking for something better, more efficient ways of doing the things they feel they but do, change is inevitable."  Is this a universal motivation across cultures and times?  For example, could it be applied to the Amish?  Is their search for water and land considered something "better"?

Again, I am limited to the introduction in my brief exposure for review, but I was heartened by the author's acknowledgement that directed culture change is largely ignored, even in standard anthropology textbooks.  I admit my bias that directed culture change has been a part of civilization from the beginning.  Could even the creation of civilization itself be considered such an effort?
