The US Postal Service is self-supporting. They are not funded by the taxpayer. So, if you simply shift all of your business to UPS and FedEx, then the USPS employees who bug you so much, won't get a cent of your money.

The USPS has some serious challenges. First is that physical mail is increasingly being replaced by electronic mail and online bill payment. Second is that the USPS needs Congress' permission to make major changes to it's service, like eliminating Saturday delivery. Third is that the USPS is required to be a universal service, it can't pick and choose which customers or services or regions are profitable or price accordingly. (Related to the second problem.)

I think mail delivery will inevitably go to 4 days a week.
