I've read all that's been posted here and I seriously tried to be non-judgemental of him as a man. Perhaps I failed.
The policies he is espousing won't work. We would ultimately end up with a world population no better off than those in North Korea or the poorest parts of China and India who used to be socialist.
I respect him as a man of God and as a scholar. He has, however, not done his homework sufficiently in worldly things to see that there is a way that God's world works down here and he is mistaken about the economic and wealth-creating part.
Creation of wealth, in and of itself, is neither good nor evil. It is simply necessary just as collecting food and water is necessary. Wealth is potential energy. Without wealth you can't give any money away to those who don't have it. Controlling that wealth in a centralized government leads to a whole world of corruption and waste. That is clear from history. Nobody's goals are reached, especially the poor and powerless. Millions die.
Theocracies don't work. Socialism and other centralized economies don't work. A world of variations on the model of a Constitutional Republic with a (mostly) free market uniting them is the best solution that humans have so far come up with in this imperfect world.
