Everyone has different wants. From my experience everyone’s wants are VERY varied. The importance of one-hundred goose decoys is high to someone who goes goose hunting like my father, but to me I would not give them a second look. Just as I am sure that he would rather keep the twenty dollars in his wallet than buy a shirt that he just knew would make him look good. We both put different values on things. I have always been quite aware of this. Different people, households, different countries, different races, and different religions values things so differently it does not seem logical.
Economically we are not logical creatures. Psychology plays a huge role in our decision-making. Without feelings what would Christmas or Valentine’s day be like? What is the point in gift giving when you may not like what you get in return if you get anything at all? Why would giving away money essentially be a good thing? Well, unless you were obligated or forced into giving someone a gift or taking them out for a romantic dinner then the answer is that it makes you feel good. People feel good making others happy. On the receiving side it is good because you have the sentiment of the other person giving you the gift.
When a want becomes more important than a need it can become dangerous. For example young girls wanting to follow the trend and stay skinny so their desire to be skinny overrides their need to eat. Another example is addiction. Any kind of addiction may it be drugs, sex, nicotine, a video game typically takes over as a perceived “need” so other real needs that are needs for health and survival are cast aside. Let’s just stick to our basic needs and maybe we will get back on track.
