I am out of my depth here. $2.7 is not nothing, but $9B is still on the books, no? No ifs and buts about it, unless our government does the right thing. Just eat the cost and prop them up, treat your federal employees right. It's really bizarre that the government expects them to turn a profit.
Tangent, having lived in 5 states, the USPS workers have always been nice and courteous, even when there are lines out the door during the tax season. And in general, like DMV or other licensing agencies.
