IF UPS had a package for every single address they would find a way to deliver it.
No they wouldn't because they'd still go broke building the infrastructure and purchasing the necessary equipment to do so. Why do you think the GOP keeps trying to basically sell the USPS to private companies? None of them can afford to duplicate the model and none of them can do it and still make a profit.
And it's not just UPS, its DHL, it's FedEX, and all the other delivery companies in the marketplace. Why do you think they use the post office for end delivery to more places than they actually deliver to?
And the USPS has seen their own package business explode because of e-commerce/Amazon, so mail itself is not the issue, it's still their delivery capability of ANYTHING to every address in America every single day of the week if called to.
My Postman doesn't stop if he has no mail for me.
But he still goes by your house every single day as he delivers to your neighbors. Other carriers don't darken your streets unless they have to, and none of them likely come 6 days a week.
In other words run it more like an actual business. We deal with the post office and I am sorry but it is a charlie foxtrot. They can't even produce their own shipping software because of the political interference...
I'll take your word about the software issues, but as I posted before, the service is not a normal business. I don't know about you, but over these last couple of decades, the USPS is just if not more reliable than the other services as it regards overnight and priority deliveries, and their online tracking systems are on par with everyone else's. I really feel that all the focus on efficiency and productivity has manifested in a much leaner and meaner service than ever before.
That is the reason all of this is so egregious. USPS has been functioning rather well, and now it isn't because of Trump.
