Isaiah 46:9-10 (NKJV), 9 "Remember the former things of old, For I am God, and there is no other; I am God, and there is none like Me, 10 Declaring the end from the beginning, And from ancient times things that are not yet done, Saying, 'My counsel shall stand, And I will do all My pleasure,'" God knows what will happen before it happens. He knew Jacob's character before he was born. God knew Jacob would value God's promises and would have faith in those promises. That's at least one reason God honored Jacob over Esau.

Your paraphrase from George Orwell's novel, Animal Farm, is not God's way. Right now all human beings are born imperfect, are sinners. God is not creating each specific person. When God made Adam and Eve, He told them to be fruitful and multiply, and fill the earth. Their children would have been born perfect had the first couple not sinned. When they received the death sentence, "Dying, thou shalt die," the dying process began. Thus, we all inherit different sinful tendencies

However, in the kingdom, all the willing will walk up the highway of holiness (see Isaiah 35), and then once again be perfected in mind and body and be restored to God's character image. Acts 3:20-21 (NKJV), 20 "and that He (God) may send Jesus Christ, who was preached to you before, 21 "whom heaven must receive until the times of restoration of all things, which God has spoken by the mouth of all His holy prophets since the world began." 

All that Adam and Eve lost will be restored to mankind. Even when all traces of sin in people are gone, there will still be an order of honor among all creation. 1 Corinthians 15:27-28 (NIV), 27 “For he ‘has put everything under his feet.’ Now when it says that ‘everything has been put under him’, it is clear that this does not include God himself, who put everything under Christ. 28 When he has done this, then the Son himself will be made subject to him who put everything under him, so that God may be all in all.’"

The hierarchy from top down is: God, Jesus, the saints, the great multitude (company) and angels, mankind, animals, plant life, inanimate objects. God knows who is best suited for a position and where they belong. God does not predestinate beings; all beings have free will. But God does know our tendencies, strengths, and weaknesses. Were God to elevate someone to a position of too great an honor, that one would find the demands overwhelming and could sin. God loves every precious person. We simply need to stand in awe of His wisdom and love.
