If you work on an older and large rails code base, you can easily find the programmers who came from more "formal" languages like java.

They build layers and layers of code to "isolate" rails and end up with big ball of mud. Once you do that you have to keep wrapping and adapting, and commanding, and querying and it takes a gang of more than 4 developers to maintain a feature set that could be done with 1 good rails dev.

Code is liability. Features are the asset. Well written rails has one of the best bang for the buck for lines of code per feature.
