"I love the Ferengi because they are sort of a 1990s or 2000s American acquisitive businessman. ... The Ferengi are really ignoble, really awful people, and they're really funny as a result. But they do change over time. When you watch the whole arc of the Ferengi in Deep Space Nine, the Ferengi, just by contact with the Federation, become more like the Federation, they become Keynesian social democrats, by the end. Suddenly you have the right to have unions and strikes, and there's health care for everybody. ... I always thought that this story of the Ferengi becoming more humanitarian just by contact with the Federation was a metaphor for all of us becoming better by watching Star Trek."
