Elon Musk and Bill Gates. Two entrepreneurs whose projects have changed the world forever and brought attention to global issues in our society. They are both business titans with a total state worth of over $300 billion.

Bill Gates could have been the world's first trillionaire if he hadn't sold his Microsoft shares and dedicated billions to philanthropy. Forbes estimates his stake, adjusted for splits, would be worth $1.

Is Elon Musk planning to make good on his pledges to primary Republicans and even start his own political party after Republicans passed Trump's budget bill?
