The phrase "the affluent become richer and the poor get poorer" perfectly captures the effect. The Matthew effect is another name for the underlying idea.

The phrase was first used by sociologist Robert Merton in a 1968 paper that described how, regardless of who actually did the work, the more eminent scientists in a group tend to receive the most credit for the group's work.
