It would be great to raise prices on spam business mailers without raising prices on normal people

Totally. It's 90% of the mail. It's junk.

They sort of do this by having the spam business mailers package/submit in ways which cost USPS less to deliver, and the discount is less than the savings. Also covers fixed costs due to volume, which is important due to universal service obligation.

(I have all my mail sent to a CMRA and basically never see any of this stuff, though.)
