There’s still plenty of corporate greed to complain about, a la attempts to privatize the USPS, as a single example.

The issue is often framed as a burden: “the USPS costs American taxpayers x-billion/trillion dollars per year”, instead of the societal marvel that it is.

Try sending a standard letter across the US for less than $1 with FedEx or UPS.

The USPS was founded before the IRS, and even prior to the Declaration of Independence. That it’s technically older than the US, and one can still send a standard letter anywhere in the US for less than $1 is a service we need to protect.
