It's not pure productivity for those 16 hours.  They leave to get lunch and dinner (and dinner is typically paid for during the week and both are paid for on the weekends).  Sometimes they run to a gym for an hour, but generally they are at the office from 9 or 10am until 1 or 2am. 
  
 Sounds onerous and it is.  For 2-4 years, those IBD analysts and associates are here all the damned time, but they do get well compensated for it.
