Saede, if you think Edison did anything out of a desire for simple knowledge and humanitarianism, you may want to read some more on him.
Okay, so maybe Edison wasn't a good example, but overwhelmingly I believe the point still stands.
Not really. Despite the "better angels" amongst us, life is inherently competitive and violent on a very basic, biological level. Although some few people do not
seem to manifest it, the drive to possess, to win, to own, even to obtain at the expense of others, is an inherent trait of our species. In fact, it is a necessary trait, selected for by evolution. A purely altruistic organism will fall victim to a clever and greedy one. An organism that accumulates more resources will increase its chances of survival over those that have less. An organism that can accumulate more resources via violence with minimal risk to itself will do so. Altruism, as a behavior, is engaged in not for some higher moral purpose, but because some altruistic behaviors benefit our own genes.
All such utopian dreams will founder on these rocks. We are predators, and we have achieved the dominance we have by being more ruthless and intelligent killers of other life (animal and herb) than any other organism on this planet before us. You cannot possibly drain the deep waters of this communal well of violence and greed, and all such attempts to create "new men" have failed, usually in orgies of blood, violence, and greed themselves.
People want to fight, to compete, to compare, and to deprive others. Capitalism (in the common sense) is a process that tries to maximize the benefits and minimize the harms of this behavior. But consider the many attempts to equalize economic and social conditions: they have all failed, as humans pursued social gains, private wealth, and, most of all, power over their fellow humans beings. Whether from within or without, every commune, every state, every society operating on the principles of economic equality and social solidarity has crumbled or will. The attempts to create them have been legion, spanning centuries. There have been no successes.
And some, like myself, do not worship the gods you do (for the literal minded, I mean that the following is my opinion), and would not have such a paradise even if it were offered. I, personally, have not shrugged off (in my belief) the false God of Christianity and Judiasm only to be informed that I now owe allegiance to another, whether it be to my fellow men or to a state. There are those among the human race who embrace what we are, embrace the struggle to thrive, who understand that the essence of life is violence, the fight to survive, and see the offer of a utopia as something not worth having.
I, and many like me, I think, take pride in the fact that the food we eat was earned by us, that the water we drink was paid for by our efforts, that we have had to budget and ration our pleasures so that we could advance our knowledge and increase our standard of living. For those in that frame of mind, a house not bought is not worth living in, food paid for by others is foul to the taste, and those who seek such benefits deserve only contempt. There is a pride and joy in living, as much as you can, as sovereign over your own existence. Life is not worthwhile, it is not worth possessing or preserving, unless it is life vibrant and possessive, self-directed and alive with purpose.
And why should I, or any woman or man who works hard, support those who
will not do so? There are those who cannot, that is another argument, and a good argument for reciprocal charity can be made. But I would not voluntarily give a fraction of a penny to subsidize the health or feeding or housing of someone who refused to make every effort to supply himself. And why should I? By what moral commandment or practical necessity? The human race does not need those who will not provide for themselves. Nor, in my opinion, should it want them.
