Dude, I am not so egotistical to think that I know the best thing for humanity, that is something each person and culture has to decide for themselves based on their own beliefs and values. I have my ideas, but the only rightful thing I can do is lead my own life because that's all I can morally control. I can seek the influence society, but I have no right to dictate. So while yes, some types of social organization may be more or less efficient than others (and I think there are some major inefficiencies with the idea of minimal government and strong capitalism in that it cannot support a large population, and dead is dead, no matter if someone kills or someone starves to death because society is messed up, both suck equally). So, yes, in a sense, it is a very small difference when you look at the number of deaths, life expectancy, and whatever it is we must do to preserve our fellow people from horrible situations.
Also, we are derailing the thread, we can continue this somewhere else if you wish.
