I'm not OP, but I can answer the question as if it was addressed to me. I believe that a lot of "real life" code can be simplified because I've had way too many cases where I open some program and remove 60 to 80 percent of its code without affecting the overall logic. (This usually includes obvious duplication, needless abstraction layers and things that reimplement functionality of standard libraries.)
The difficult part usually isn't the restructuring itself, but understanding what the program is supposed to be doing in the first place. Fortunately, deleting code is one of the best ways to learn about what it's doing. You need some good tooling to do this safely, though.
