Legalese

I sure would like it if Lady Justice would talk in a language that the ordinary man could understand. According to Merriam Webster, legalese is the formal and technical language of legal documents that is often hard to understand. 

Why would anyone use a language that is hard to understand?  Whether it's the warranty information on a technology device, your cell phone contract, or the terms of medical insurance, it's all written in legalese.  It also is written very tiny, aka the fine print OR it is several pages long.   

I've been encountering documents with several pages that seem to repeat the same things over and over again.  Written in simple terms, they would state questions like these:  What color is the sky?  The sky is blue? Who helped you determine the color of the sky? Please admit that the sky is blue? 

My question is this:  Why ask for information that is already known?  Legalese - a language that makes understanding so difficult that the ordinary man is forced to employ the services of the person who wrote it to interpret it.   ---- That's called job security for the legals.
