I'm not sure I'd want to see that. Privatization isn't always the answer. And FedEx/UPS have their own horror stories.The best thing that could happen would be to let either UPS or FedEx absorb the USPS. Then it would be properly managed. Then the USPS could get modernized and better able to handle the high volume.
Warning: Rant ahead.
The assumption by many is that nobody uses the USPS to send letters or pay bills anymore and that everyone is doing such things electronically and that packages should be sent by private carrier.
But many areas of the country still don't have what we would call broadband service and many in the lower socioeconomic strata don't have ready access to computers or tablets. The digital divide is real. Besides, FedEx and UPS don't serve many areas that the postal service does - it's not worth it to them.
Most of the problems faced by the USPS are political. For example, those same members of Congress trying to kill the service managed to pass legislation (several years ago) requiring the postal service to fully fund its pension system 75 years into the future. No other company has to do that - anywhere. Talk about having one arm tied behind your back.
Then, only a year or two ago, Congress forced the USPS to cut the price of a first-class stamp by a couple of cents - because the postal service turned a profit.
And many of this year's issues can be tied to political moves surrounding the election. I'm not going into detail here because I don't want to upset anyone - nor criticize their political point of view. But most Americans reading this know what I'm talking about.
The problem is, the USPS is a quasi-government agency. Most of the lifetime employees of the postal service know what needs to be done and can do so. We just need to get put up a political firewall and let the USPS do is job.
End rant... and thanks for reading if you bothered.
