It may be that you've been unlucky. I've been using Clojure for nine years now, and the majority of codebases I've worked on have been very clean. My experience is that Clojure tends to produce flat codebases, whereas OOP languages produce codebases that tend to be deeply nested. I can't prove any of this; it's all anecdotal, but I thought I'd mention that your experience might not be typical.
