Who was more valuable, the tool maker or the tool user? The tool user created value, but the tool maker made it possible. And do we need to consider the parents of each, for their part? These are probably well discussed in philosophy. My answer is that the civilization that produced the tool maker and the tool user is more important, because of interdependencies, comparisons of great contributors is problematic.
