It is a luxury, but I don't think we're wrong to want luxuries. I think the frequency issue is intentionally disregarded. And it shouldn't be. I'd rather have weekly delivery to my door than daily to a community mailbox. But what I'd really like is choice. What if we had both a community mailbox and weekly door-to-door delivery? Need something urgently, pick it up at the community mailbox where it gets dropped off daily, but if you're not religiously emptying your community mailbox, a postman still comes by once a week to deliver any mail from your community mailbox to your home?
I suspect this could potentially save a lot of money AND provide actually better service to the significant majority of people. To the point that we could even start expanding door-to-door delivery again instead of removing it, we'd just expand it to areas that currently only have community mailboxes but do it on a reduced frequency, like garbage and recycling services. If they can do it weekly in most places, why can't the postal service?
