Business
A market can be among the world's largest without many big spenders: it can be built from huge numbers of people each earning and spending only a little. The size comes from the count of buyers, not the depth of any one wallet.
Serving a market made of tiny transactions means designing at very fine grain: small amounts, small differences, small segments. Strategies drawn at broad scale miss where the demand actually sits.
Shared digital infrastructure that handles billions of small, individual transactions a day gives the tiny shop and micro retailer tools once reserved for large firms. Real change then comes from below rather than from the top.
