Frameworks are a major contributor to these dynamics, which is a little unfair to blame on the language, but I've seen orders of magnitude difference.

I had one time it was faster for the three of us to rewrite a web app in Rails than to make the Play framework accomplish what we wanted it to accomplish, even though none of the three of us had ever worked in Ruby before. Rewriting four months of work took two weeks because Rails neatly supported what we were doing and so much could be generated. We ended up with better test coverage too.

You are correct but nothing can be done about it IMO. PLs live and die by their "killer apps" and that is most of the time the framework du jour.

There are refreshing exceptions here and there but there's also something to be said about whether it's a good thing that frameworks don't dominate a certain PL (like Golang; everything is very readable if verbose but one does get tired of generating the same boilerplate all the time).
