A top assistant prosecutor at the Southern District of New York or Main Justice today makes around $150,000 a year. In 2016 the government scale topped out at $160,300. A top partner at a good firm can easily make $3 million to $4 million a year. In the meantime, the cost of living in the nation’s most coveted and powerful cities has skyrocketed. A prosecutor’s salary has become more difficult to live on, while in private practice a partner’s income has dramatically outpaced inflation.
