There is at present a conspiracy of silence around the economic system we live within. We find it hard to change its bad sides (or defend its strengths) because we simply cannot understand how it works. Nothing captures this more than that we currently study maths when, in truth, we should really (from a very young age) study the one thing that maths is used for by 99% of the population: money.
In the Utopia, there would be extensive classes on the workings of Capitalism. One would study how profit occurs, why some areas of activity are much more profitable than others and how economic opportunities arise.
