I know that France is the butt of many jokes about work, "no French word for entrepreneurship," but in my experience almost every business I interacted with around socialist Paris was a small, independent business. This was the unintentional consequence of labor laws. <50 employees fall under one set of labor laws, >50 employees you're in a tight spot until you're >1000 employees. Then the additional overhead of benefits for those employees is subsidized by economies of scale.
