Age: 33
Occupation: Former Goldman Sachs employee
After over a decade at Goldman Sachs, Smith decided he'd had enough. But he didn't leave quietly. Instead, he published a scathing resignation letter in the New York Times accusing Goldman of betraying its clients; the missive seemed to confirm the worst stereotypes about the powerful bank. Alternately hailed as a truth-telling hero and condemned as a disgruntled back stabber, Smith immediately became a flashpoint in the ongoing debate about the role of Wall Street at a time of widening income inequality.
