> The other half is that agile makes you iterate through pseudo productivity before you actually understood the problem, accumulating cruft that you need to maintain and extend as you go on. I wouldn't be surprised if of the productivity that is left, more than half gets wasted on crufty software structures and writing code before you understood the problem.

I've seen this increase proportional to the number of employees. People start trying to worry more about perception of progress by tracking proxy metrics, because the large the company, the harder it is to prove how each one contributes directly to the bottom line.
