Investment used to mean putting up capital to create or own something that, with some work, would return a stream of income. Farmland produces food with the work of farming. A factory produces goods with lots of people working. A mine produces iron or copper with lots of machines and effort. With the financialization of the economy, lots of people are increasing their "wealth" by speculation and skimming a percentage on transactions. When people start believing that speculation is the only form of investing, society is in for a hard fall at some point.
