"Better" can be meant in a number of senses. Contemplation is "better" in that it is
analogous to our final end, that is, contemplation of God Himself in beatitude.   As pointed out, your interpretation elevates academia over actions.  As also pointed out, this is a gross misinterpretation of the biblical story.  A perfect example of the kind of intellectual gymnastics that have brought academia into such disrespect.
