Poor education quality or "false" education is, in my opinion, the reason.

There are people who benefit from the society's problems like war lords, false "soldiers of God", corrupt politicians...etc. Imagine how many of such people would so badly want to keep the truth hidden from the public. True education is about knowing and making people see things the way they are which would deprive the corrupt in power from their control over the society.

Added to your points, there is also the matter of "irrelevant" education.

In addition, the problem with society is not that we lack the human and material resources required to make the world a better place but because many leaders of society are more interested in personal gains and power consciousness. Corruption becomes entrenched and bad governance becomes the order of the day. The inevitable outcome is that millions of citizens are subjected to dehumanizing living conditions while a few, the elite, enjoy the best of what society can offer.

Flase education results in not only ignorance and lack of proper academic knowledge necessary for civilized societies, but it results also in fostering a rotten social structure, a superficial society that goes by appearances. A hollow society, to sum up.

In addition, the symbiotic relationship between character [moral] education and knowledge education is fragile; hence, most educated elites that manage the public, private and civil society sectors in most societies have very weak moral and ethical fiber to do the right thing for public good. Having educated leaders without human conscience in the position of authority is dangerous to the society. Education must be holistic - character and knowledge.

Also, there should be synergy between education and value system in the society as well as collaboration between educational institutions and communities and the private sector to enhance the positive impacts of education in every sector, including governance and economy for common good. As a result, educational institutions should contribute in solving identified problems within their domain, thereby promoting demand-driven learning outcomes.
