EastBank....what % of the mail is mass/junk mail and what % of revenue does it provide? I am making an assumption here so bare with me, but I would imagine that personal mail service represents a very small % of total mail and most people are able to receive and pay bills electronically, so it appears to me the postal service is being used primarily to deliver mass/junk to homes that eventually ends in the trash.
I couldn't give you exact numbers but from personal experience it's far more advertisement oriented mail now. The majority of businesses and older people on my route still prefer to use regular mail, especially because of fears of online identity theft.
Many companies give you the paper / paperless option these days. Then again, as I tell customers, anytime that you do anything electronically, be it on the internet or do things such as using the electronic ticket counter at the casino, you're potentially taking someone's job away. Consider that the next time that you gripe about unemployemnt or people on welfare.
