Please define "worth".
Please show how your claim is correct (hint: it is wrong)
or not - many powerful people have to work so hard for their power that their reproductive success is diminished.
Yep.
So you say - but you have already admitted that power is not equal to reproductive success: "has a lot to do with" is not "equals".
Also, social darwinism calls for actively selecting - where does the ToE say humans should do active selecting?
I guess you have no clue what social darwinism really is, nor what evolution really is.
No, I think your the one thats confused about what evolution really implies, or maybe you don't want to believe it because it doesn't fit your moral beliefs. Evolution selects those traits that are most likely to be successful in reproducing. There is no guarantee that each individual that it select will be successful at doing so. A trait that tends to gain a lot of power in humans is more successful in general than a trait that does not gain power. Therefore evolution and natural selection is going to pick that trait. That trait is in essence 'superior' to a trait that does not begat power.
Your nitpicking at my post while ignoring the overall point.
Power and reproductive success are strongly positively correlated and it is a casual relationship, its not a coincidence. You'd have to be blind to say otherwise. Power makes it more likely that your genes will be passed on. It is not equals, but its pretty darn close. Looks at Kings, emperor, nobles. They generally slept with more women and sired more kids than your average peasant.
Humans are actively selecting every day. I don't agree that a government should put more pressure for them to do so. But to promote that humans are equal or even close to being equal on the individual level is also ludicris. Government should not go either way, it should not force them to select what is "genetically superior" but it also should not be encouraging integration either. In this matter, government should stay out and let things take their natural course. Same thing with hereditary wealth and such. You should not be trying to promote a class of elites nor should you be trying to promote equality. You should just let things play out as they are.
Do the rich and powerful have more children?
Actually yes, in the long run. Gheghis Khan has 16 million decendents. Your average person from the 12th century does not. Their children are more likely to survive at least and be in positions of power. Kings, emperors, and rulers, generally tend to father more offspring than your average Joe. Its not quite as true in western society today because we've made rules to prevent whats natural from happening out of feelings of "fairness". But you can easily look to other areas of the world where leaders like Bin Laden for instance have far more wives and offspring than the average person. The powerful also control all the resources and in times of crunch are the ones most likely to survive.
Not all 16 million have his level of power obviously button they don't need to. Having that many descendents is quite good insurance that his line will continue to be passed on.
How ironic, then, that societies have progressed towards fairness as reason took over from religion.
No, it was actually religion that drove forward the first sets of laws that made order. Religion is basically the center of all our cultral advancements. Without it, we've still be in the stone age.
