When will schools start teaching what is needed?

OK, to start I am not putting down teachers or schools.  Most of the teachers I have come across really do want to make a difference in the lives of students.  The real problem lies with the fact that we are teaching kids how to get good grades, how to get an A, how to pass a test and how to write down information from a book or the Internet in a nice neat package.
I have come to realize that what we really need in the workforce and in life is the complete opposite of what they teach in school.
I am working with people who are afraid to make a mistake because they still think they need to get an "A", when what they need is to take a chance and maybe get a "C" but at least try something new.
The best work is the stuff that lets you stretch, forces you to grow and take chances.
The school system wants kids to write neat, answer the question the exact way in the book, memorize the answers so you can spit them out.  We need people who scribble and guess and take a chance with the outcome in order to really produce something great.  It seems like an impossible dream.
Perhaps we need an antischool before joining the workforce or the artist way?
