this is really the invisible giant. Things like machines which manufacture machines for instance. a good friend of mine works at a glass blowing company which makes beer bottles, the machines used to create bottlecaps at an insane rate are apparantly dominated by a german manufacturer. (this factory produces over 15mil bottles a day). producing 15 million bottle caps in a single 24h shift is hard, producing stuff this quickly at suchs a scale is a hard problem to fix.
