To try and simplify my editorial for Mr. Hamby, wasn't about whether the Postal Service lost $15.9 billion or $16 billion last year. My point was the whole controversy is about the funding of the pension system that Congress mandated, and Mr. Stossel never even mentioned!
The Postal Service actually earns a profit each year. It's just that it's impossible to meet pension funding that Congress strapped on the Postal Service. That's why they show a loss.
