The USPS is the only postal service (in the 1st world anyway) that is not subsidized by the government. The congress mandates that the USPS carry mail (3rd class-business and non-profit) at a loss and the congress is supposed to make up the loss-they never do(surprise!). In 1989 or 1990, the congress took over one billion dollars from the USPS to put into the federal pension plan. That was to replace the money the congress stole from the postal employees in 1969-1970-the congress took the money deducted from the employees paychecks and spent it for the war. If the congress were to give the USPS what they owe it, it would be in the black.
