The Post Office’s Biggest Problem Isn’t Saturday Delivery — It’s Congress It may seem like the United States Postal Service is unwilling to adapt to a world of declining mail volume and increased digital communication. But the real obstacle in the way of true reform aren’t the folks running the postal service itself. It’s their bosses in the U.S. Congress. Postmaster General Patrick Donahoe is like a man waiting for a package that never arrives. Donahoe, who has led the U.S.P.S. since 2010, has over the past few years made numerous proposals to get the money-losing postal service back in the black.

Below are three other ways Congress has halted postal reform. Congressional inaction: Pre-retiree health care. The costliest problem for the U.S.P.S. is the Congressional mandate that it pre-fund healthcare for future
