Postal Rates rise basically because Oil (petroleum) prices rise. The USPS should perhaps change the consumption type from petroleum (in case they use that. i do not know what they use) to other alternatives like: biodiesel, ethanol, butanol, natural gas, vegetable oil, biomass, and even chemically stored electricity (batteries and fuel cells).
i am not saying they have to change the whole fleet. engines can be adapted to be able to move with green technology.
and perhaps with that change prices drop to 37c ?????
