In Discipline with Respect, Chapter 1, "The Principle of Purpose," I discuss the importance of building responsible behavior with tasks and responsiblities appropriate for a child's age. It does take more time than doing a job yourself, but parenting includes helping children become mature and responsible adults.
I recently saw a post from the American Counseling Association (ACA) about chores. The suggestions are similar to mine.
Here's a quote from their post.
Having your kids do assigned chores can be an important factor in helping them develop in positive ways. Chores are a way for a child to feel part of the family, and to gain a sense of contributing toward the family good. These early life lessons make it easier for a person to feel like an active, contributing member of society later in life.
And here is the link to the ACA blog so you can read their Jan 05, 2018 post about the value of having children complete chores.
