My theory, you'll think it's nuts. They have been reverse engineering alien technology for decades (search Bob Lazar or watch any of the Steven Greer movies like "unacknowledged" or Contact of the 5th kind, etc). They now have the required tech and expertise to operate the planet without much of a population. If the tech gets out into the wild, that will destroy their control mechanism like this absurd monetary system and remove much of their power. Free energy takes away much of the need for people to go to work and would clean up our environment. They want to control the world so they can control their family wealth and future, just like these banking families have done for centuries. I think it's all linked and likely to the secret societies and dark arts as well. This isn't a complete thesis, but covers much of what I'm thinking is going on here.
