ELI5: Why is the USPS expected to turn a profit?

I’ve seen a lot of articles recently about the overhaul of the US Postal Service after a 2.2 billion revenue loss. Why is this government agency expected to turn a profit while other government agencies are simply given an operating budget?

It's not supposed to make money, it's supposed to break even.

However, several years ago Congress became worried that sales were turning down.  The Post Office employees have very nice government-like pensions, and with less sales the Post Office wouldn't be able to afford these pensions at some point.  Congress required the Post Office to prefund its pension liabilities, unlike every part of government, over a 10 year window.  We're in the middle of that now, and the huge losses at the Post Office are because it can't make enough money to run the Post Office  **and** fund all these pensions.
