I think no issue is given greater attention in the Bible than is wealth, and specifically the accumulation of wealth. The prophets (Amos among the most caustic) saw in the accumulation of wealth and in the refusal to share that wealth the clearest statement possible of Israel's religion: It wasn't fear and love and trust in and of God; it was fear, love, and trust of riches. And how many times does Jesus warn of the dangers of money and its accumulation?
Keeping in mind that I think the economic challenges of the world (including consumerism, greed, graft, hording, mean giving -- to name but a few) are of far greater theological significance in the Bible than with the gender of a person one sleeps with in a committed and "faithful" relationship, you might find this commentary, which appeared on The Forward's weekly newsletter, to be interesting. I think the (note: conservative) author's call for foundations to expend themselves within 50 years to be intriguing and in the Biblical spirit!
