Natural selection gives traits that are good enough for survival up to the time of reproduction. There is no value to be gained by being anything beyond just good enough to survive and only till reproduction is accomplished. Natural selection is about being “good enough” and there is no force which drives towards excellence. Fast enough may, in fact, be much more successful for descendants than fastest. Strong enough is good enough and there is no advantage necessarily accruing from being the strongest. The forces of natural selection are quite satisfied with intelligent enough and do not persist towards increasing intelligence. The equilibrium position is mediocrity.
And so it is with democracies. Democracies are all about winning elections, not about selection of the “best” leaders. A winning candidate only needs to be sufficiently intelligent and sufficiently competent and sufficiently rich and sufficiently cunning and sufficiently dishonest to ensure the capture of sufficient votes. There is no value, and there may well be a negative value, in having more of a vote-winning attribute than just necessary.
Given that excellence, of any attribute, must be a minority “thing” (the bell curve again), any system promoting the majority must inevitably promote a leveling down – a chase for mediocrity. Natural selection is all about increasing population. Extinction is failure and increasing population is the measure of success. Democracies pander to the majority in a population. There will always be more of the poor than of the rich, the unintelligent will always outnumber the intelligent and the incompetent will always swamp the competent.
Excellence in sport requires special coaching and training regimes for elite squads of young athletes. Academic excellence requires elite academic institutions. Excellence in science needs its ivory towers. Excellence in companies is achieved by autocracies (including monarchies) but never by democracies. Military excellence requires elite troops. Excellence in government and in management requires autocrats. To achieve excellence in almost any field requires elitism. “Socialist principles” abhor elitism. It is not perhaps so surprising that the essence of “social democrats” lies in leveling down, in making a god out of mediocrity.
At some point humans and human societies will find the need to drive towards improvement and a search for excellence. With no pressure to increase population humans will be freed from the constraints of natural selection and will be able to target excellence. Natural selection will have to be given direction with a strong dose of artificial selection. Once poverty is eliminated (but not the poor who must always be there) and population is stable or declining, even human societies will be freed to chase excellence. Democracies will then need to acquire some spine by institutionalising more than just a little whiff of autocracy. Voters and candidates for election will need to qualify, votes will be weighted and elected leaders will be autocrats for their terms of office.
Leaders might then begin to lead again rather than being followers of the mob.
