The video starts covering shifts in supply and demand from the consumers perspective, along with elasticity and weighing costs and benefits in the first verse. The chorus poses the question "Why you always changing?" to the market, and uses some of the fundamentals of microeconomics to respond. Concepts in the second verse range from the cost, supply, demand for labor, to luxuries and necessities. The third verse finishes with some fundamentals of microeconomics such as rationality, subjective costs and benefits, secondary effects, and holding all else constant.
