They should raise the price on postage for the advertising circulars they deliver (and that take so much of the mailman’s time to stuff in boxes).

Could be a good solution; the idea is that “Standard Mail”
(”junk mail”) is given to heavy volume mailers at a discount
to encourage them. Personally I try if at all possible
to opt out of junk mail (mail preference service)

btw another big cost for USPS was the installation of machines to detect anthrax after 9/11 (two postal employees
died due to anthrax). There is a procedure should anthrax
be detected at a facility.
