Okay, can someone please explain to me what diversified and Islamically sound investments look like: [1]What would they be? [2]How would they work? [3]How accessible would they be - would everybody have equal access or would the current system carry through (with only a small percentage of people holding vast amounts of wealth, resources and power)? [4]How sustainable would they be? [edit: preferably those investments that would allow and promote halal exchange between Muslim and Muslim (and anyone else we would need to deal with) and would allow and promote the communal health and stability of our entire ummah. In brief/point-form, plain, easy to understand, layman's terms please.]
