Actually that's not true. Economists have very diverse views of what economic efficiency entails. Remember, not all economists are rabid, right wing, Liberal voting ideologues.

Samsung,

Perhaps you could refer to a recognized economist that deviates significantly from what I described. I would be very interested if you were able to dredge up a name, and am waiting with bated breath.

Whilst there may be some difference of opinion in how to achieve it, economic efficiency is simply achieving economic activity with the least of effort.

While you may call me names, if economics is a science, what I see here are the flat earthers, who have no clue as to reality and who are debating what to do at the edge of the earth. It is actually quite pitiful.
