With private companies there's a lot of inefficiency that comes from having to have competition. Without competition you'll have monopolies, and combined with the profit motive those are a disaster. But to enable competition you need to have multiple organizations doing exactly the same thing. That's a lot of unnecessary "overhead cost" that you get by having duplicate products, duplicate management, duplicate HR, duplicate everything. You also have to build a brand, do marketing and other competition related things that don't actually contribute to the product itself and which would be mostly unnecessary without competition. Add to all that the overhead cost that is profit and the amount of waste in a public organization whose goal is not profit and that doesn't need to compete doesn't sound so bad.
