I have not taken a statistical analysis, but it seems that many times, when I get to the job, the device I am installing comes in an unopened package. More often than not that package was not of recent purchase. Sometimes it was not even purchased by intent, but was picked up at a yard or garage sale. This means that another person purchased it and perhaps never got around to having someone like me come over and install it. Often its present owner got it on impulse and uses my talents to finally get the item put to use. This points to a pattern of making purchases that perhaps do not reflect true need.
I am more familiar with a pattern of when a need arises, a tree of decisions is made that will lead to that need being met. In this manner most purchases are made deliberately and with need in mind. Along in the flow of decisions, comes its being put to use. That way, a need comes up, a plan to fulfill that need is developed and carried out--done deed. But when a purchase is made without such preplanning, no path to have that purchase utilized is in place. The snag of not having the ability to conduct an installation means the item may never be put into use hence its appearance in garage sales. I surmise that somehow purchases are made without a preplanned need. Apparently some force other than need is making us consume goods. I wonder how much work, I would still have lined up in front of me should folks all of a sudden decide to stop making rash purchases. I do not see our economy grinding to a halt despite the warning that if we do not keep the wheels of industry churning out goods, economic disaster looms.
