You sound like a doctor complaining that today's medical schools aren't graduating any decent brain surgeons. The truth is that medicine, like CS, is a very broad field of study. Your primary schooling is not intended to teach you a specialty, but to teach you the basic skills needed in a cross section of specialties so that if needed you can later be trained (probably OTJ) as a specialist.

The only difference between the medical and CS industries is that the medical field recognizes the education for what it is and has instituted very carefully crafted programs to mentor and train young, incoming doctors and help them identify a specialty that fits them and then build their skills in that specialty.

In CS it sounds like the senior personnel prefer laughing and pointing fingers to actually mentoring and training their personnel. That HAS to cut into the productivity seen from many of the younger workers.
