No it's because you are 20. Has nothing to do with having a real jobs. There are a lot of silly arguments in the last 15-20 posts.
There is a huge portion of the population that is over 50. These people count on the mail much more than you and I may.
These are also the people who, believe it or not, still write letters, and mail all of their checks and bills via. the USPS.
City mail everyday and suburban mail 3 times? Think before typing.
I hate to see people lose jobs, and especially that many. The plain fact is that the writing has been on the wall for years as far as the post office's demise. They also should have started their cutbacks well before they did. The problem is.... it's a government institution, which means it gets to die the slow death, whilte keeping people employed as long as possible. Whether this is seen as admirable or wasteful is up to your own opinions.
Yes the slow death and the continued survival of the post office is at the expense of the citizens of this nation. You say it's fully funded by postage, but who pays postage? Individuals and businesses. And, as postage has tripled since I was born, and gone up 66% in the last 20 years the burden has been placed more on the population to support the PO. The problem is, people were already shifting away from the mail for many things. From communication to paying bills to buying goods and services.
I've known a few mailmen in my time, and I'd hate to see them looking for work again. I also am old school in some ways. I like reading my news and books. I have plenty of things delivered to my home. It's the junk I don't want. I'm all for less distribution centers and smaller post offices, but I don't see them yet completely going away. They just need to be better at adapting.
There are 2 massive post office buildings in my City that I think at least the massive downtown footprint could be bulldozed with 5 or 6 new buildings taking it's place with a small branch located on site. There are still always big lines of people at city post offices believe it or not.
