According to this article from FastCompany, over half of the world's total share of wealth is now in the hands of 1% of people. In other words, the very rich are very very rich indeed. Much of this is due to the rise of stocks and other assets and the stagnating wages paid to workers. I am posting this not because I have an answer, or because I am pushing a certain economic philosophy. But it is a problem of deep moral concern, which I think it is incumbent on those of us concerned with justice, and on the religious specifically. I'll go ahead and quote the well-known (but perhaps too little pondered) verse from Matthew:
The slavish devotion to wealth is clearly opposed to a devotion to God, as shown through acts of Love, Justice, Generosity, and Justice. What this report tells me is that the forces that love money more than God's people are doing extremely well and this drives deep injustices in our world. This is not new. But it is getting worse.
