Purchasing and selling is a course of study, especially economics. You either go to university to acquire this knowledge or do an apprenticeship on the market. Money is moved by knowledge, not by itself. Today, you don't even get one percent a year if the money is on your account, so in trade, knowledge is capital. What is a thousand euros worth of investment? Judges, police officers, commerce traders, and civil servants: looting and espionage, sabotage, murder, and violence are ape-origin business. Today, with "I want," "you want," "know nothing" extras? Scum, disgrace.
