No - it's a natural product of competition, the pressure of which exists regardless of your legal structure. A sole proprietor running a courier service will need to differentiate himself relative to the other courier services, and the potential customers of such services place immense value on timeliness. Even if the courier were a non-profit, for it to be selected in favor of a competing service it would need to choose the basis upon which it wanted to compete and excel at it. USPS is sufficient for many things (e.g. 70% junk mail), but it's not a market competitor. Where it matters, there's a need to differentiate to survive. When our business needs something overnighted fast and reliably, it's always a private carrier for a reason that doesn't involve its legal structure.
