Each rung represents not just a wealth band — but which types of capital you hold, which you are denied, and what that determines about your economic trajectory. Capital mix drives outcomes.
Core thesis: Wealth is not a number — it is a capital mix. Moving up the ladder requires acquiring a new type of capital, not just more of the same type. A working-class person who accumulates more physical labour capital does not become middle class; they become a harder-working poor person. The transitions that matter are qualitative — credential acquisition (Tier II→III), first investment vehicle (Tier IV→V), network activation (Tier V→VI), and structural capital formation (Tier VII→VIII). Each of these transitions has a wall — a structural barrier that is rarely about individual effort and almost always about access to a system. South Africa's persistent inequality is largely a story of those walls remaining intact across generations — documented by the Gini coefficient consistently above 0.63, the highest sustained inequality on earth.
