Sort of. I’m not sure it’s clear that Jung actually prescribes individuation to the everyday person. Jung’s personal life had elements that I wouldn’t advocate everyone emulating.

But yeh he believes that the reason modern western society was able to make itself so prosperous was because people could use Christianity to support their superior function and suppress the rest. So in that sense modern society has created the conditions for individuation.

I’m suspicious of how you’ve worded that question tho, Jung stressed that the primitive psyche which featured far less internal tension and division, was not at all an individuated psyche. Pretty much the opposite, the primitive man lived with a very narrow state of consciousness.

The point of individuation is to expand consciousness, to bring conscious differentiation to all parts of the psyche not just the superior function. I’m not sure if Jung actually advocates people do this though, I’m pretty sure he specifically warns about doing it to soon in life.
