Does this mean ability to read, write, and do arithmetic? Does this mean the ability to speak and read Latin with an understanding of the classics and the Bible? The ability to fix a car and build an engine? Program a computer?
One could argue that a university does very little to make a populace more educated, since they can already read, write and do basic math (or should be able to) to get into school. Is taking psychology making one better educated? Maybe? Maybe not.
It's not a "congratulations, you are now well-educated" mark. The more educated the population is, the better. Now, at some point there are trade-offs and diminishing returns (if your entire population is busy studying philosophy and everybody starves, that's bad), but considering how much absolutely worthless shit society dumps money into, we have plenty of slack.
Well educated isn't so clearly defined: In general, though, it is having been exposed to a varying number of subjects, be able to read a varying amount of things, have enough general knowledge that they can understand the reason there are "chemicals" in food and the reasons not to mix some household chemicals together. In addition, the person has been able to dive into a particular subject more deeply than the other ones, and understand that other folks have different specialties. While doing this, you are generally exposed to an array of people and if your institutions are fair, they come from mixed backgrounds.
Realistically, the basic information will be similar (basic science, health, reading, history, and so on) but we'll have different areas of interest and skill, so the exact subjects will be individualized to an extent and will definitely change over time as the world changes. You can't say for certain that psychology will make you better educated, but an introduction to the basic field might open someone's mind to being educated in that field, which helps society at large. Other things will be more esoteric: Go to art school, work in retail, and happily make art doesn't have the same sort of immediate payback - but chances are, they are more likely to be a bit compassionate just by having the education.
I am not sure if university is an effective place to do this. I think tricking the younger minds at primary/secondary school to be more curious and well-rounded person is much better. Once you get the ball rolling, they will hopefully keep being that way into their adulthood. For example, how do you teach a young adult to be kind when they aren't? Teaching them about kindness via multiple sessions of lectures ain't gonna cut it. You would have to "trick" and "manipulate" them into being so to bypass ego/whatever else which is much harder to do for adults.
No matter how curious you are, you tend to benefit from learning from others. There is more to university than learning from books. You wind up being around folks you wouldn't otherwise be with. For some folks, it is their first experience being without supervision. And stuff like that. It doesn't need to be university for all so long as there is some sort of schooling that meets these needs for folks. We can start doing adult-lite at 15/16 and have people move into dorms their last couple of years. Doesn't mean that a lot of folks wouldn't benefit from university or something akin to it: A chance to have an intensive course learning another language, for example, with the goal of fluency.
You can't force anyone into being kind, and some folks are simply going to be sour. We do start teaching folks as children, after all. Make peace with the fact that some individuals aren't going to be: That's OK so long most folks are and it shows in society and programs that help others.
