I think the love of anything is an indication of what is in your heart. A mother does everything for her child obviously because of love of child in her heart. The one who loves the worldly things tend to prefer them over other things. He strives with a bent of mind to attain those things. The more he strives, the more pleasure he gets and that puts him in a satisfactory state. Since money is thought to be a prime source of happiness so people tend to achieve more and more wealth. If you think it’s not that good then cultivate true love of God that in turn nourishes love for the humanity. If people on earth lives with a heart full of humanity, than there will not be chaos and uneasiness in the society. Human rights violation is nothing but a resemblance of human heart void of humanity.
