I think that I need to clarify that I did not mean that God guarantees complete equity amongst the people of the world. After all, this would mean that the Earth would just be a giant space-station. It is quite clear that God has left to the world, meaning the universe, to its devices and freedom with only religious writings to help guide us to the true path. Thus, there would be natural inequalities due to the variety that this freedom can provide. For example, it is harder to find food in a desert as opposed to a forest.
I know you did not mean that, but I was alluding to location, i.e. where we are born, which we have no control over. This is a difference we all have to deal with.
