Question: Why is it that in most routines that the deadlift is the least utilized lift? For example in Starting Strength, you deadlift 1x5 every other workout but squat 3x5 every workout. And while the bench/press are rotated every other workout, they are lifted 3x5 and the DL is 1x5.

Does it have to do with CNS stress? Or is the squat just considered a "better" lift?
