No, she’s not right. She is expressing the quasi-religious belief held by leftists in general that history is evolving naturally and inevitably toward the Marxist utopia, but this is false. Human cultures do change over time, but apart from divine intervention, the change is toward whatever the aggregate of individual self-interest produces as a target. In that sense it is undirected change, and can as easily slip into patterns of chaos rather than order, or harmful order versus beneficial order. It is this delusional faith in progressive social evolution that sustains the left in doing irrational acts such as opposing natural variation in outcomes. Their “faith” enables them to idealize these harmful, irrational acts as somehow, magically, building toward that utopia that can never exist under the rules of reality. The Marxist genocides all come from this. But it is false. Human nature tends toward entropy, just like everything else. Unless God helps us, we tend toward chaos.
