Employment in the industry has fallen just 8 percent since last September. Only a handful of big hedge funds have closed. Pay is already returning to precrash levels, topped by the 30,000 employees of Goldman Sachs, who are on track to earn an average of $700,000 this year. Nor are major pay cuts likely, according to a report last week from J.P. Morgan Securities. Executives at most big banks have kept their jobs. Financial stocks have soared since their winter lows.
