In short, the central thing about job creation from young companies is its inevitability. It is a species of mathematical certainty (one driven by initial simplicity and a wall) that young companies must create the most jobs (even without assuming particular skill on their part, or taking into account sectoral or economic growth, both crazily conservative assumptions). That the drunkard’s walk applies to the economics of young firms is an mind-altering realization (in a good way), one that helps put the messy data of company and job creation in a more plain and meaningful context.
