If the USPS raises their rates then the business will go to Fed Ex, UPS, and their own delivery service. People in rural areas will pay more for their deliveries of everything because if the Post Office gets killed off the competition can jack their own prices up.
It is congress that is killing the post office.....it will not let them close some post offices or cut delivery to five days or some places less..
Most people get and pay bills online....they could deliver my mail once a week.....ninety percent junk mail....
