The education system is falling behind the students 15 years ago
I agree with the crux of your post. However, people hone their communication skills on a daily basis, simply by interacting with the people around them. Having a strong pedestal in math and science rely heavily on the educational system. A solid background in these areas make it much easier to understand more complex principles, and to think clearly and logically. It's important to communicate your thoughts coherently, but your ideas, themselves, are more important.
