UPDATE: A State Department official, requesting anonymity, writes in to revise the original statement:
“This reference to 42% applies only to the local staff at the embassy in Ethiopia. After a three year wage freeze economic conditions in various countries around the world have resulted in varying increases to a number of U.S. embassies. U.S. law requires that embassies compensate their local employees according to prevailing practice. So while Ethiopia will receive an increase, along with another 75 or so posts this year, there remains a larger number that will not get any increase since the labor markets in those countries do not show that increases are warranted.”
