Why is the state interested in ensuring that all citizens are educated?

One of the most important tasks of the state is to raise the level of education of the population. This contributes to the general welfare of the country. As you know, educated people commit less crimes. If the majority of citizens are well educated, the cultural level will rise, there will be less chaos in the country, more respect for each other, people will realize their importance, albeit small, but will strive for the better. But it is important not to force a person to get an education, but to interest him in the learning process and great opportunities in the future.
