This is also a congress-made problem as they privatized the USPS and created this pointless exercise of making them turn a profit, while being regulated like no other company (because that's us admitting we need mail).
Which I don't get because the USPS is authorized in the Constitution.
The corporate agenda of the past several decades has been to destroy the Constitutional government (which is the only thing bound to our narrowly-construed Constitutional rights) in favor of ceding authority to unaccountable corporations.
