Didn't mean to comment about Post Office, but I did. The point is finances in private industry and government are different. The first is sorta true, government is politics, not to be taken serious on a financial basis. 

Every government level is questionable at best.

I stopped trying to understand government finances. 

It's is amazing to me the system continues. Hope it goes on the rest of my life. Let my kids worry about it later.

Can you imagine a politician actually telling the citizens that 2 + 2 = 4.  It's just the way stuff works.
