An economy is what makes a little into a lot.
You manufacture, do the value added shuffle, i.e. make dirt into iron, iron into steel, steel into cars, etc.
You speculate, i.e. buy low, sell high. Labour, commodities, etc.
You invent, i.e. create something from nothing, i.e. software.
Economies are the property of the nation, they feed the people, provide lifestlye, and challenge the mind. You get reward based upon effort.
