As an educator, my standard answer is going to be that there's never enough training and education.
What you want is to provide people with a rich enough range of educational experiences. Sometimes, yes, the school of hard knocks and learning on the job is part of that, but what you ideally want is to have the training take place ahead of time and to have it give people a real enough sense of what these problems are like so that you go past either just reading an act or reading it in a textbook.
