The numbers support my case. You can send a mail with the USPS for 50 cents anywhere in the country, but it costs $5-$10 to do the same with UPS or FedEx.

Literally 10x-20x costlier.

Government just doesn't have to waste money on things like profit or marketing that private companies need to do.

USPS is a private entity under the government, they fund themselves. They receive no funding from the government.

You can look at the military and at obamacare/heathcare.gov for examples.

You can also look at the USPS as an example, since it IS a government entity that doesn't have to serve profits.

Also, the military and healthcare is more efficient in government, but you probably already knew that already.
