This is just to have a handy reference available when arguing how many angels and which ones are dancing on the head of a particular economic pin. OK the standard definition: economics is the study of the production, exchange and consumption of goods and services. Why do people spend an inordinate amount of time getting lots of goods and services? Well according to anthropologists and evolutionary economists this is a less violent way to engage in kin selective behavior. Well less violent than the political behavior of give me what I want or I will thump hell out of you and take it anyway. So what is the point of piling up stuff beyond the $10-20/day needed to provide a reasonably balanced diet and other necessities for a family of four? Even doubling that amount to $14.6K keeps you well below the poverty line, yet people sleeping in their cars and living on that amount of money can be found across the country and living fairly well by world and historical standards. So the question is why when living in the lap of luxury by any reasonable standard are people discontent with a minimum wage job? The answer according to biology is that all of the rest of the work and expenditure people engage in is mating display either for themselves or their descendants and is no different than the territorial displays of birds, fish or insects except in sophistication. Economic arguments do not involve basic survival needs or mating displays are wrong.
