The US Federal Debt could use the cash.

Why is the US Government in the delivery business?

Why do I have 4 delivery trucks driving down my street every day but I have to walk to the mailbox to get my mail?

Here is an idea.

1. All the delivery services deliver packages to a local Post Office before noon.
2. Post Office sorts the packages.
3. Post Office delivers the packages and mail in the afternoon.

As a result, the gas of 3 delivery trucks is saved which helps the environment.

Oh, and I do not have to walk to the mailbox.
