congress should allow USPS to raise rates if need be, but how would amazon force USPS to make special, money-losing trips just for them? most (all?) rural packages should go out with the regular (usually daily) mail carrier, so the marginal cost of also delivering amazon packages to rural addresses should basically be zero for USPS. for the really remote areas, i don't think you can choose any time-bound delivery you want, like next-day or two-day. they would only quote you what they'd be able to manage with the normal, likely less frequent, delivery schedule for the area (like weekly). so i can see how USPS misses out on lucrative urban deliveries, but not how they lose money on rural deliveries. amazon absolutely does gain by not delivering to rural though.
