It's simple, but 'experts' in any field love to make things appear more complicated than they are. Be wary of anyone who starts a sentence with "look, it's a very complex area with no quick fixes", because they are usually ignorant or they're protecting their position.
If I can make something look complicated, I enhance my position. Since I'm the only one who understands it, I must be special and in-demand. I ensure my paycheck and status this way. If the problem is seen for what it truly is - ie. simple - then I lose all that. I have an investment to protect, and that investment is me and my wage. Virtually every profession does this. Having a special lingo helps entrench rarity value.
I would post some more but I'm extremely busy. Hang on, I have 3 phones ringing, and one is my broker. See what I did?
