You'd think, but...

If the problems been around a while, the people who caused it have since been elevated in the organization. So, them and newer line managers, who should have seen and solved the problems earlier, are mad when somebody identifies a problem. When the person who found the problem then fixes it, they're even madder.

I worked for the federal government. There's a philosophy in government that if you solve too many problems too fast, you might be out of a job.
