>Yes, set aside liabilities for 75 years in the future. They effectively have to fund people before they're born, unless you think they've got a lot of workers who'll be there over 75 years old.
They have to set aside money to pay pension obligations that they have incurred to their current employees. No money is being set aside to pay pensions for workers who have yet to be born. A tiny fraction of the money set aside may be paid out in 75 years, but it won't be to a worker that has yet to be born. It would be paid to a current USPS employee that is still living 75 years from now.
>So, yes, they have to fund. And they're struggling because they're being subject to deliberate and malicious political attack on public services.
For other reasons, perhaps, but not for the pre-funding requirement.
