"Reading fail. The (obvious) point the OP was making is that the vast majority of snailmail is catalogs and other junk mail,"
Thinking fail. You haven't ever received a mail in rebate, an ebay package, a small business online order, a care package from grandma, letters from the bank, local catalogues from small businesses, cheques from contract work, reminders about doctor visits, city forms, etc.. recently?
And besides all that, do you really think that the destruction of a carrier will stop or decrease the levels of spam? HA! all that money there, UPS and fedex would be more than happy to enter that market. I doubt you would see even a one day drop in spam volumes. Someone like UPS would buy up the usps business and then charge the average person $7 to send a letter. The volume discounts would likely not change and you would be at the same place you started, except on the rare occasion when you do need to use the service and then you would personally pay a lot more.
Its hard for me to believe that the federal government doesnt own the post office as a government service. Its one of those businesses that should not be run as "for profit". They are providing a service at a low cost to everyone in your country and should be protected.
" Hence your "old ..and poor people" are subsidizing the corporations."
Nice try there sparky, but here's a fun arithmetic fact. 10000 items at 5 cents per item is vastly MORE MONEY than 1 grandmas letter at 2 dollars or whatever. Obviously the advertising industry drives the post office's revenue. You can argue that this is wasteful, environmentally unfriendly and therefor the federal government should really probably pay for the post office to prevent these sorts of spamvalanches, but you are not doing that. You seem to be saying that snail mail is obsolete, which i think is demonstrably false. There is quite a high premium to send things by fedex or ups, thus creating a good niche for USPS, albiet evidently not a profitable one. Should near universal access to a communication tool be profitable? thats the question.
