Just because it's broken, doesn't mean you should fix it.
The U.S. Postal Service was invented in 1775. Of course there wasn't email, the internet, FedEx, DHL or UPS. If you wanted to get a message to someone, you either sent a telegram, wrote a letter or yelled really loudly. That system worked (more or less) for a long time. Now, it's been disrupted, to the point where staying the course will lead directly to mounting debt and degraded service. Making adjustments to something this broken is a futile undertaking. Especially when the alternatives are already in play.
Time to abandon and start over...or maybe just abandon.
