Suggestion: I completely agree with Xi and I actually used this point but my question is where do you consider money on your pyramid? Money can be used to purchase anything on any of the levels of the pyramid, so I would just consider money and answer how you would address this concern. There may be more than one way to go with this but money must be defined in your own terms to avoid potential objections. Question: My critical question is what you believe to be vital needs of humans? Can you give an explanation to your answer to this question?
