The Pareto "principle" was a crude, snapshot observation--which predicts nothing (even in "Pareto" distributed income clusters. The subsequent Pareto distribution, which by itself is nothing more than math, predicts nothing and is a special case of a family of related functions. Pareto didn't even derive it himself.
