The main difference between your "zen" languages and your "kitchen-sink" languages seems to be whether they've standardized their basic libraries, or whether everybody brings their own. I don't think it's controversial to say that virtually all programmers use libraries (both built-in and third-party).
Javascript and Scheme programmers don't build everything from first principles, and C# and Lisp programmers don't need to study for years more just to figure out which wrench to use. The working-set of programmers in either kind of language is comparable in size and functionality.
