Unless your job is primarily to clean up somebody else's mess, your debugging time is a key part of a career-long feedback loop that improves your craft. Be careful not to shrug it off as something less. Many many people are spending a lot of money to let you forget it, and once you do, you'll be right there in the ranks of the cheaply replaceble.

(And on the odd chance that cleaning up other people's mess is your job, you should probably be the one doing it; and for largely the same reasons)
