Allow systems (aka people) to grow at a healthy pace instead of forcing them to mature on your schedule, because it is detrimental to the overall health and well being otherwise.

Unfortunately because so many people grow up with different experiences and privileges, and we lump all people together in state institutions, ie school, it necessarily means you cant tailor curriculum to individual students, but instead have to act as though everyone is equal and has the same experience. So naturally many kids are forced to compete with those that have unfair advantages and therefore we inevitably end up forcing some percentage of kids to change/learn/mature faster than is natural, because, you know, we as a nation would rather spend money on war and dysfunctional subsidized corporations than educating people effectively.
