Actually, it does. If they had businesses that scaled, they'd be well above the million-dollar mark and in the even-tinier minority. But I'll go one further and suggest there's a causal link in play here: The half that are business owners are people who make their money precisely in businesses that don't scale. They own and operate local businesses which are natural geographic monopolies and they don't get crushed by large multinational competitors because of that fact. For example, these are businesses like landscaping companies, local shops, construction contractors, and services businesses. Also note that a chunk of the 50% that don't own businesses are well-paid, sometimes independent professionals such as doctors, lawyers, architects and engineers. Again, their source of income does not scale, so they get rich by cutting costs.
