Greg Smith has gotten his 15 minutes in the spotlight recently for doing something most of us can only dream about — quitting his job in spectacular fashion. The former Goldman Sachs executive's resignation was coupled with scathing New York Times op-ed lifting the curtain on the alleged toxic culture inside the investment bank.

Already, the shockwaves of Smith's editorial have been felt — the former executive director alleged some management at Goldman Sachs referred to clients derisively as "muppets"; CEO Lloyd Blankfein later said his staff was conducting an internal investigation into the matter — though what long-term impact, if any, it may have on the firm remains to be seen. For Smith, to be considered a true patriot of change, he'll have a long way to go to measure up to these whistleblowers — eight businesspeople who stood up and changed their companies for good.
