In the late 1800s, a half-dozen or so super-wealthy would regularly vacation together on Jekyll Island (Georgia USA), representing some 1/6th of the world's wealth. Expanding the total to include the top 85 would probably produce about the same results as Oxfam's report over a century later. That a few of the richest (with vast holdings) out-value half the world's population (with zero, or negative, holdings) at any given point in history is not surprising.
