You are being creative in your use of the term, “efficient.” The USPS are losing gobs of money—they are the picture of inefficiency!

Efficient ~ i think just compared USPS to the rest of the world. Almost all foreign postal administrations subsidize their post office operations. The US doesn't ~ and at the same time we have the lowest prices.

I think you don't know enough about the topic to discuss it.
