My understanding of Plato's cave is that it is about the disparity between the ideas in our head and reality. For example, you know what a triangle is, but there is no such thing as a triangle in the world, only imperfect shapes with three sides that approximate a triangle. This means that it is not "most people stay in the cave" - it is, "we all stay in the cave because it is impossible to bridge the gap between theoretical construct and lived experience, but we all know about both".
