When hiring depends on who you know and not what you know
When people are rushed because they are afraid of being fired from their phony-baloney flying jobs and having to get a real job digging a ditch or hauling trash
When people are too tired to pay attention to what's going on around them because they have to do a bunch of bullsh*t on the job unrelated to flying
...then these kinds of things happen.
Now there are solutions for all of these problems. But they involve the Government telling rich people what they can and can't do. So you don't like that. Conclusion: Welcome to Hell.
