Isn't their logic confusing latency and throughput? Not enough mail to deliver suggests less mail volume, so less need for throughput, therefore we can hire fewer postal workers per post office. Cutting out one day of deliveries reduces throughput and increases latency. For example, Netflix becomes a worse deal. A power user could once cycle 2 roundtrips of DVDs in one week and is now down to 1.5.
