You are a victim of mis information. Yes the post office has lost personnel correspondence business. But they have more than made up for it in flat rate shipping. The reason they lose money is under the Bush admin. They were forced by legislation tagged on to a completely unrelated bill that they had to provide retirement medical benefits for the next 75 years in 15 years.
This legislation was imposed to break the USPS next we have a big USPS smear for people who do not follow or research legislation to believe. The sad thing is this huge lump some of money is being wasted
buy those who passed it.
So If you want your postal carriers to make minum wage and if by free market you mean the buddy system for government contracts go ahead let the current system be back stabbed out of existence.
You can see the lies and mis information they spread in something as trivial as a ecigs. So why would you believe anything from this self serving money consuming laviathio that will stop at nothing to feed its self.
