A large problem with metrics is that they have a tendency of becoming a goal of their own. Instead of them being used as mere indicators, we end up with entire countries whose sole goal is to eternally increase their GDP - to the extent that it ends up harming the general population.
People do not solely exist to generate revenue, and it is about time we stop pretending they do.
