If you do not hold your leaders to a particular limitation, they will, due to human nature, automatically attempt to extend their power. State control is by nature inefficient because it lacks an efficient incentive mechanism. If you work from such assumptions, no wonder you are a libertarian capitalist. Economic efficiency can mean high unemployment or diminished services . That is a false statement.
Economic efficiency means that production is at maximum, while cost is at minimum.
Unemployed persons cannot purchase goods, hence the company loses, and it is no longer operating efficiently . Economic efficiency in a free market automatically results in lowered costs and a higher standard of living, for everyone, because of the availability of goods and an increase in available cash. Society is a NOUN, a term indicating a localized collection of individuals. You need to add some sort of verb to it that can be efficient - like, productive output, or something like that. A group IS, it cannot be efficient or non-efficient, any more than a pile of rocks is efficient or not.
