Your argument seemed to have more than a single point. And you said you proposed strict control. Any kind of call for action that you propose is weakened considerably by not having a plan of action. You are applying my argument to the wrong point of yours.
But I'd argue that all you're doing in the current system is hiding behind ignorance of who actually can succeed or not. I'd say that for some people the advantages others have are insurmountable, we just can't see it because it isn't such an obvious disparity as the one proposed.
In particular, if you look at the future as an inevitable consequence of the current state of affairs, there are clearly people who will not succeed. And I'd argue that that is how the universe is, the future is already essentially determined. Our actions are determined. Our successes and failures are determined. Clearly every last person who failed didn't have the ability to overcome the advantage. If they did, they would have. If you claim they were not hardworking enough, then I'll just point out that their environment and genes did not make them that way, so in essence there never was a way the could have succeeded.
Besides, you've done nothing to dispute my example of the vegetable. He is unable to match us. Does that make our existence unfair to him? By your logic it would seem to. To him we might as well have godlike powers. It needn't even be so far as a vegetable, just need someone who is severely mentally disabled. Is our existence unfair to such a person?
So? That's a problem for society. Doesn't make it unfair. They were just born that way. Just like we are born more capable than some unfortunate others in society.
Shouldn't be genetic? I'm going to say that's ridiculous, Presume we're in a world where it already occurs. That would be the same as saying that "Well that's not fair, this world shouldn't have cancer". It's fact, it happens. Saying it shouldn't be that way is nonsense, you're complaining about the way the universe is.
It is entirely dissimilar from monarchy and despotism because those are a choice.
And your talk of needing to rely on others, so what should we do about the people who are too weak to live on their own in our society? Are we an abomination because we have so much more power than them?
