Does any of that mean we need to lie and pretend that there's 100B pieces of useful mail being delivered? Just because there's a lot of useful mail doesn't mean there's 100B of it. That number shouldn't pass anyone's sniff test.
I haven't seen any indication that it's a lie. Please post a link to the proof.
Is not a lie simply because it doesn't align with your political view.
Note that what you consider junk mail, other people may find valuable. I know someone who digs those ValPack coupons.
Someone else posted some links in this thread already. But OK here: https://www.uspsoig.gov/sites/default/files/reports/2024-09/...
No, and nothing I've said implies any agreement with the person whose nonsense you were countering. But you were countering it with more nonsense.
