Regarding the Feb. 14 editorial “Patching the Postal Service”:

The premise that the U.S. Postal Service is hemorrhaging more than $5 billion a year is false. This “red ink” is the product of an absurd burden placed on the Postal Service to pre-fund future retiree health benefits 75 years into the future. No other federal agency or private business faces such an insurmountable burden. Without this mandate, Postal Service operations ran an impressive $3.2 billion profit the past three years.

Bipartisan legislation working its way through the House is a positive, though imperfect, step forward as it addresses the pre-funding debacle. Rather than support this growing consensus, The Post called for further reduction in services with an end to six-day delivery and undermining the well-being of dedicated workers by limiting collective bargaining rights.

The Postal Service is a national treasure. It daily serves 153 million addresses with no direct taxpayer dollars. A vibrant public Postal Service remains critical to the sharing of information, binding the country together and for the success of e-commerce.
