"Not everything that counts can be counted, and not everything that can be counted counts."
Albert Einstein.
I've never been materialistic, and my wee Gran used to say "There's someone who knows the cost of everything and the value of nothing ...." about people who were/are extraordinarily motivated by 'things'.
How I see it is there must be something in this idea if it captured Albert Einstein and, much more importantly, my wee Gran's ideals.
