Why do we (🇺🇸) still have the mail?

I remember a Seinfeld episode about this years ago, many years ago, before Amazon and Jeff Bezos even existed. Seriously? With email, FedEx, UPS, etc, why do we still use the mail? I think the only time I send something is around Christmas time. And the difference between the mail and FedEx, UPS, etc. You don't have to pay for FedEx and UPS unless you use them. Whereas the mail is paid with our tax dollars. What are your thoughts?

People in other countries reading this? What are your thoughts for your country?
