I had a realization that the very existence of private domestic shippers in countries indicates a failure of their government to provide universal infrastructure needed by all citizens.
There may be specialized needs like same-day couriers, special handling requirements and other edge cases, but those should be small specialty houses, not international mega-corps.
A fun little doc about your selected shipper(USPS), their corruption and pursuit of profit.
A postal worker is harassed and fired for standing up to a toxic culture. His son’s powerful documentary exposes how the USPS was systematically dismantled for profit — at the direct expense of the people who keep it running. A gripping true story of courage, corruption, and a system that turned on its own.
