Well, when a company has various activities, the direction/management decides that a company must focus on a single activity ("focus on a single trade and be expert in it, delegate the rest" is then their motto). Then when a company has a single activity and is an expert in it, the direction/management decides that a company must have diverse activities, be it vertical integration to decrease the costs, or horizontal integration to reduce competition, or just invest/acquire in totally unrelated sectors to eliminate risk. And then back to step one, and so on. The only constant goals in all this seem to be: 1. to justify firing employees and lowering working conditions; 2. to generate artificial activity for all the direction/business/finance sector, so that they always feel both useful and powerful.
