The Chinese government has reduced crime rates there by killing and enslaving those who commit crimes, even in lesser categories. It's harsh but effective. I'm not recommending that approach, merely pointing out what has worked.
It is a myth, on the other hand, that an ever greater education establishment reduces crime rates. Educational levels in western nations rose dramatically from late in the nineteenth century to the present day, and so did crime. Today, unemployment is stubbornly high because jobs have been taxed and regulated out of existence partly (in substantial part, based on public budgets) to spend more on public education. Educating people for nonexistent jobs has no impact even were that fictitious correlation between crime and universal educational activity to exist.
