Private owned vs. State owned” is the wrong debate. State owned monopolies do not perform well even if they perform moderately better.

Can this generally differ from country to country? I tend to agree with this in the sense that state owned monopoly tend to reach economics of scale as a result of large patronage, hence it's a no-brainer for whatever service they offer to be cheap. This doesn't mean because its cheaper than state owned that it might actually be better.
Nigeria is run and controled my private monopolists who are paying hugely to the government to be in that positions, what do I call this? Since its in between state and private?

However I believe private monopoly to be worse especially since there are no systems put in place to actually checkmate the excessive maniplulation of price to make more profit. Private monopolists are why entrepreneur are not given patents in the Nigerian market structure.
