The episode introduces “middlegarchs,” owners of private pass-through businesses whose collective wealth exceeds that of highly visible billionaires. Treasury researchers linked top incomes to businesses such as car dealerships, restaurants, manufacturers, and dental practices, revealing how much wealth is concentrated in ordinary local industries. The episode then follows entrepreneurs who built fortunes by finding market opportunities before examining how their wealth and representation in government helped secure favorable tax treatment and regulations. The fight between Tesla and South Carolina car dealers shows how middlemen can preserve their position, limit competition, and affect consumer prices.
