The expression 'Money can buy happiness' are completely biased based on linguistic and symbolic interpretation, and are dependent on the definition of the word 'happiness'. In this realm most people exclusively associate 'pleasure' with 'happiness', which is both stupid and counterproductive, in the sense that there obviously are two different words invented for the different states of being. Money cannot buy happiness, but it can buy pleasure and thus a temporary sensation of wellbeing. But this causes addiction as pleasure do not last long or remain. Money can also not buy knowledge, as that is only acquired through studies, nor can it buy wisdom, as wisdom is acquired through experience. Money can however buy composed information in terms of intellectual expressions which you can study to acquire knowledge, or experiences, which then can be transmuted into wisdom. True happiness arise from realization through knowledge and wisdom and do not cause addiction, as true happiness is a form of fulfillment and lasts as long as one is not distracted away from it because of addiction; as to say, addiction to anything that promotes temporary pleasure eradicates true happiness if the pleasure is not part of experience or studies. Money is a tool for progression, not a measurement of success nor accelerator of happiness. Likewise, friends are not the true source of happiness, it is the intellectual information exchanged and the mutual experiences accumulated that transmutes into lasting happiness. But if one becomes dependent on another in order to feel happiness, that is neither friendship nor healthy, as it is another form of addiction. Addiction destroys true happiness; whether it is to drugs, money, friends or anything else.
