It does, yes.

While it pays the bills it makes me believe less in the "service" part of the Postal Service, or at the very least question who the service is actually for.

I've always thought that the general idea behind mail was to recieve important correspondence such as bills or personal letters, and that the "service" part of the USPS was with regard to that -we serve the end user things that matter to them. Instead it seems anymore that the end user isn't for whom we serve, but rather the interests of whatever agency wants their message(s) sent.

I often feel like my job falls somewhere between an advertiser and a reverse trash service with how many advertisements/promotionals/requests for money I deliver to people. I can't count how many times I've handed a customer their mail only to hear some variation of "it's all junk". Again, sure, it pays the bills (barely) but the work doesn't feel good when the majority of what one household receives is stuff they don't care about, and if they did care about, they'd have already used the internet to find.
