one percenter

A one percenter belongs to the wealthiest one percent of a population—the ultra-rich whose wealth vastly exceeds ordinary citizens.

The term gained prominence during the Occupy Wall Street movement contrasting the one percent with the ninety-nine percent: The one percenters keep getting richer while wages stagnate.

Separately, in motorcycle culture, a one percenter is an outlaw biker—from the claim that ninety-nine percent of motorcyclists are law-abiding.
