An adept representation of a limited sample of the issues surrounding customer support and similar departments.

The problem is that it doesn't have to be like this. There are exceptional cases where customer support is not like this. Many of them have gained considerable benefit from investing in their customer support. One source of difficulty is that evaluation of those benefits requires very complicated (for an average middle manager) mathematics and causal modeling. There's no simple metric that measures the real benefits of good customer support, even tangentially.
