I call bullshit... They receive $100 million in tax dollars per year to subsidize blind and overseas citizens. They also get $18 billion per year in tax benefits. That is not self-funded by any stretch.
They have a multi-billion dollar loss because the GOP Congress passed legislation requiring them to pre-pay their employee retirement health benefits instead of funding it on a pay-as-you-go basis.
Given that the USPS is a government established and run service, thus backed by the USG in terms of its liabilities, the idea that somehow the USPS is "saving" this health benefit money somewhere is ludicrous.
It's just as stupid as the SS "trust fund" and "lockbox", which is nothing more than a paper shuffle of US treasuries from one drawer in a filing cabinet to another.
Is having the funds to pay for retiree benefits a terrible thing? In CA, most of our pensions for public employees can barely even meet current payments.
I agree about the mess of the social security paper shuffle though
