Wall Street’s run of prosperity extended into the first half of 2021 with $31 billion in pre-tax earnings, beating 2020’s outsized first half profits of $27.6 billion. Despite continued strong profitability, employment in the industry in New York City has sagged, even as it has ticked upward in the rest of the nation. Average salary, including bonuses, reached $438,000, the highest of any industry and nearly five times higher than the average in the rest of the private sector.
