Felix Salmon nicely explains “how Congress is killing the Post Office.”

What does make a lot of difference is the degree to which the Post Office is hamstrung by Congress. There’s still room for the Postal Service to reorient itself and become a successful 21st-century utility — but there’s no way that’s going to happen if it’s constantly on the back foot and if Congress prevents it from entering new businesses, possibly including banking.
…
To put it another way: the Post Office is broken, in large part thanks to unhelpful meddling by Congress. And it won’t get fixed unless and until Congress gets out of the way and stops forcing it into the corporate equivalent of ketosis, essentially consuming its own flesh in order to survive.
