Since in thousands of years of human history no system of government has brought such conditions upon humanity, I prefer to be more realistic and wait on the promise of our Creator.
Ecl. 8:9 All of this I have seen, and I applied my heart to every work that has been done under the sun, during the time that man has dominated man to his harm.
This is what the God of the Bible, the One Abraham, Moses, Isaiah, Jesus, Paul, believed in, will do for humans:
Rev. 21:3 With that I heard a loud voice from the throne say: “Look! The tent of God is with mankind, and he will reside with them, and they will be his people. And God himself will be with them. 4 And he will wipe out every tear from their eyes, and death will be no more, neither will mourning nor outcry nor pain be anymore. The former things have passed away.”
