In the years before the insane pension funding fiasco, the USPS actually was making a profit. Then Republicans passed a bill that the USPS, unlike any other federal agency or business, had to fully fund the pension benefits 75 years out. This was a blatant attempt to kill the USPS, in favor of businesses like Fedex.

If Democrats win it all, they could change that to more reasonable requirements and then the USPS would be profitable again.
