#29: Elon Musk
There have never been as many billionaires on planet Earth as there are billionaires today. It might not seem like they have much power other than having billions of dollars, but if we have learned anything in recent years, it is that money has a great amount of power, especially on the world stage.

New Twitter CEO, Tesla, and Space X founder Elon Musk is a ruthless man. How could anyone get as far as he has in life without being a little ruthless? His ex-personal assistant, Mary Beth Brown, worked closely alongside Musk, proving herself for years. When she asked for a raise, he fired her shortly after… So much for company loyalty.
