Sometimes I wonder if the real subtext is "we have such high turnover that almost nobody was around when the first system was designed. We rewrote it in a new language, and now we're all much happier because we all understand it much better, having been involved in its design." Wait a year, repeat.

Being a hold over employee through 4 rewrites I'd say that can be one factor. Another is that the business landscape changes too. So all these factors combined make it difficult to say for certain which of them had an objective impact.
