I have not witnessed this anywhere I've worked. It might just be a problem specifically in the department and/or on the team you work with.
Just observations. Maybe you can consider hitting them with a rod like the Cajun did in the old days. Since the implication is that it worked for you, you never know...
If the hitting doesn't work, maybe you can revise your hiring process so you're not hiring so many nitwits. Trust me, they come in all ages, colors, and sizes. If you're surrounded by these inept workers, it sounds like a problem with your hiring process. This is not a problem with young workers, only a problem with the younger workers you happen to be bringing in.
