I feel like it’s only gotten to be a time pressured, low interaction profession in urban areas where economics is against community. It might still be a great job in smaller towns.
It's the other way around, economically speaking. The expensive routes that lose the postal service money are the rural ones. If they only delivered within and between cities, they be okay. (And if one political party wasn't bent on their destruction they'd also be okay. Obviously I'm speaking about the US postal system here.)
Agreed, and anecdotally, we live in a very large US city and know our postman and our UPS delivery guy. It's been extremely helpful on more than one occasion, he even personally texted me when I wasn't home to say he could come by later. I always love chatting with them on the stoop.
