What would you do if you were not allowed to get an education? You couldn’t read or write. You had to work a minimum wage job at a factory and you weren’t happy with the job. You couldn’t teach your kid any skills because you didn’t learn anything.
The biggest part of growing up is making the right choices that benefit you in the future. The idea is to get an education so you can choose a career, have hope, and reach your goals and dreams. Education is powerful because without it, early civilizations would have struggled to survive and thrive as a culture. It is important that adults trained the young of their society in the knowledge and skills they would need to master and eventually pass on.
The evolution of culture, and human beings as a species depended on the practice of knowledge. When cultures began to extend their knowledge beyond the basic skills of communicating, trading, gathering food, religious practices, etc, formal education, and schooling, eventually followed. Schooling in this sense was already in place in old times.
