The first is, as others stated, remove the ludicrous requirement that all retirement be pre-funded for every employee (even ones who may not make it to retirement, or wouldn’t qualify for full retirement since they only worked part time). That gets a lot more money in circulation.
Rather than removing automation that makes everything cheaper and faster, add more.
Next, look for other funding opportunities. Sell things (as they already do to some extent, but should do more of.) Consider adding services that other postal services provide, like how Japan’s postal service includes a postal saving system–essentially a bank.
And, finally, it’s a government institution. It’s one of the few that is Constitutionally mandated. So it should be funded in the way most other government institutions are, via the government’s budget, which comes from taxes. If it hits on hard times, and nothing else works, just fund it directly. Or at least give government loans and such.
It’s ridiculous how utterly hobbled the USPS is right now. The point of dealing with it the way DeJoy is doing is to hobble it even more, then pointing out how ineffective it is, thus justifying defunding it even more.
Even in its hobbled state, it functions better than most package delivery services. It actually delivers nearly every package I receive where I live. The USPS has the infrastructure to do so even out here, unlike the commercial package carriers. They hand over their packages to the USPS to do the actual delivery.
And in a world where ecommerce is booming, there’s no reason it should be having so many problems. Traditional mail (letters and envelopes) may be down, but everyone buys things online nowadays.
I am genuinely hoping Biden/Sanders’ first reconciliation bill will include things to help the post office. It’s money related, so they should be able to.
