it is important to notice that the meritocratic ideal is about mobility, not equality. It does not say there is anything wrong with yawning gaps between rich and poor; it only insists that the children of the rich and the children of the poor should be able, over time, to swap places based on their merits—to rise or fall as a result of their effort and talent. No one should be stuck at the bottom, or ensconced at the top, due to prejudice or privilege.
