Laundry Detergent

I just read an article about laundry detergent, in which the author argues that Americans use vastly more detergent than they need to use. In fact, it seems as though washing one's clothes without any detergent at all is almost as effective as washing one's clothes with detergent, since the agitation of the washing machine does most of the cleaning. Moreover, the more detergent one uses, the more leftover soap scum is left on the clothes after washing. For some reason, I find this issue fascinating.
