Just for fun, spent a little internet time looking into corporate enterprise sizes, and
why they tend to follow a power law, with such a heavily skewed distribution. In other words, is there a universal law that governs such things?
Some current theories involve the structure of very complex networks, and how a few nodes in a network (in this case, the global market economy) tend to build up a disproportionate share of relationships, creating a hub-and-spoke structure, eventually leading to market dominance of a few firms (idealized chart below).

Any other ideas or insights into the "why" of the heavily-skewed distribution of corporate enterprise sizes?
