More exprienced developers spend more time refactoring code? Does that mean that they're working on crappier code, established code bases, or higher end applications where tech debt really matters?

Conversely, are the younger guys spending less time because they don't know any better, working on small projects where tech debt isn't a priority, or working on completely new code.

My guess it's a reflection of the type of work being done.

The more less experienced developers you work with, the more time you spend refactoring the code they write.
