>1. You always know how much a standard letter will cost, no matter where it's going. If you're mailing 100 letters to 100 locations, they all cost the same. Standard exemptions apply for rate changes every few years and for heavy items. Computers can figure this stuff out pretty quickly. People who mail 100 first class letters to 100 locations already either use an automated stamping system or they take the letters to the post office. >2.

I'll be paying for it eventually, either through income taxes or through higher postage rates.
