Why isn't anybody trying to fix the system so it would be more efficient at directing people to the jobs they would be actually good and happy at? To me it seems this (using the human resources the optimal way) becomes more and more important nowadays. And I believe the formal education one has completed can only serve as a hint to what the best job for him is and not a direct definition of that.
