How the Postal Service Loses So Much Money

“A key problem here is the assumption that businesses operate on a cost-plus basis. This kind of thinking is a result of how warped government operations are, which frequently engage in cost-plus kinds of contracts. Cost-plus contracts are where the government agrees to cover all the applicable costs of performing the work plus a guaranteed profit. These forms of contracts are relatively unusual in the private business sector, where bidding on price are the primary form of activity. Because of the nature of cost-plus, and how they will frequently go over-budget because there is little incentive to control costs of performance, companies generally don’t engage in them. This means, in the world outside of tax-funded activity, the USPS has to compete with other package carriers like UPS and FedEx and doesn’t have the luxury of guaranteeing itself a profit on every activity.“
