It's the commoditisation of education that is responsible for it's inadequacy imho, if I may suggest an answer to that question. Education is a kind of energy, which is dealt out in narrow specialisms, and nothing more, to ensure it yields maximum energy of profit in return for minimum education given, by the collective of people depending on the system of education to obtain the energy they need to live.
To me the Jungian shadow exists also in collectives. It might be that realising something like it in ourselves is necessary to defuse it's effects in the collectives we might be members of. It follows that the collective effect is amplified as the mathematical square of the number of members in the collective, or tribe (Metcalfes law).
Again it all looks dependent in turn, on mathematical sign of energy that it all runs on.
The Jungian shadow might not be possible on mathematically positive energy - the latter is literally the energy of the sun, the only energy added to the planet. When our consumption of energy as a species moves over to this, as it has to in every plant after the plant forms it's first leaves, maybe we will have eliminated the collective Jungian shadow, just by every individual knowing their own.
Maybe this is what is needed.
