I think dpd ha hit on the crux of the issue. People feel entitled to Saturday and door service. While I understand the sentiment I think it is a horrible reason to stick with the status quo.
I think the apathetic perception of what 1 billion dollars actually is has become so bad that people look at a $5 billion loss and say "It is only 5, it is worth it to have mail on Saturday and not have to cross the street to retrieve my mail"
Really? $5 BILLION is a massive price for those small luxuries. Especially when things like Social security and medicare are on the chopping block.
I think people need to stop saying 5 billion and start saying 5000 million, it just sounds bigger.
