What I see are committees of people who mean well but have little to contribute except pre-formed opinions, if that. Solutions of committee-level decisions are usually pretty obvious, once the facts are in, and we don't need six people to figure that out. I acknowledge that in your dream committee of thinkers, you will get even better decisions than my hypothetical wise person can come up with. I say, appoint good decision-makers and then get out of their way and let them work. My theory goes on to say that, given one or two seriously capable people who could handle it, the whole of community government could be efficiently handled by one person or a small committee, using these same guidelines.
Dictators have coercive powers.
They not only make decisions but force them on other people, willing or unwilling. I don't know why people will never let me use those powerful, attention-getting, provocative terms, just because they're not accurate. Well, all right. Have it your way. Anyway, the essence of my argument is that decision making is a specialty, like auto mechanics, house building, or accounting.
