Well reasoned for the most part, but Lisp has occupied the high ground for development tools for a long time (REPL, SLIME, trace/untrace, step, describe/inspect, room, macroexpand). Other languages have been playing catch up in this regard as well. Whether Lisp still occupies the high ground today is unclear, but it is erroneous to say that Lisp programmers envy the development tools of other languages.
