> I'm claiming that Java has a long history of enabling factory-farming software development, whereas Clojure doesn't lend itself to this style.

Any hugely popular language would have a lot of crap written in it, and a non-popular language wouldn't have "factory-farming" simply because it's not at the needed scale. So any non-mainstream language would almost by definition not lend itself to "factory-farming" development. You could also say that a lot of good stuff has been written in Java, and not as much good stuff has been written in Clojure, and conclude that Clojure doesn't lend itself to writing good stuff.

Any comparison between languages with at least 100x difference in popularity is meaningless, especially as no large bottom-line effect of programming languages has been found.

> the pool of Clojure developers will yield you higher-skilled programmers on average than the pool of Java programmers

Which matters if you're picking people from the pool at random. If not, you want to have the pool with the greater number of higher-skilled developers, not higher average. It's like saying that it makes more sense to start software companies in Finland than in the US, because on average people there are much better educated.
