If people find it difficult to practice what they are being taught in school, that shouldn't stop them from learning other skills that can be productive to them, their are many skills that one can choose that will be suitable. Not everyone ends up in practicing what is been taught in school, most people after school they get any skill and make it a career. I don't see reason why people would allow what they learned from school that they can't practice stop them from learning any skill.
What is being taught in schools were just a part and those are basic things that makes a person eligible to get into a job. The job market is different and it is a must to keep ourselves prepared for what is being required. Here we might experience difficulty in finding opportunities as well as making business. It is our ability and the understanding that brings success.
