Explain why this difference between the inner and outer core's density exists?

Metals and the frequency in which they're found influences a lot since different metals have different densities. Heat also influences a lot since hotter things tend to be less dense though the inner core is more dense.

The inner core is more dense because it's liquid and hotter, and since it's liquid the earth's movement makes it difficult for the inner core to be less denser than it is.

Hope it helped,

you did not attach the discourse, but i assume it to be the discourse on the origin and basis of inequality among men (the original titile in french is: "discours sur l'origine et les fondements de l'inégalité parmi les hommes"), also know as "second discourse". in this discourse, jean-jacques rousseau emphasizes that private property is the basis of all inequalities.

therefore, what enabled the old regime to maintain as long as it did was private property.
