Why can Musk be compared to Benjamin Franklin? Well, a quick look at Musk's resume will undoubtedly drop your jaw and help you understand why. At age 44, Musk has a net worth of $12 Billion . The five main "Big Creative" companies that helped accumulate this wealth are Zip2, PayPal, SpaceX, Tesla Motors, and Solar City. Elon Musk has been either the co-founder or sole founder of all these companies.
If you have not noticed the trend already, Musk's current three companies (Tesla, SpaceX, and Solar City) all have a focus on sustainability. Elon Musk's intention behind starting all these companies is what I believe to be most telling of his character. In an interview with CNN, Musk stated, "the philosophy behind all three companies is to try to minimize existential threats" . By promoting and revolutionizing the sustainable energy industry, and pathing the way towards making life multi-planetary, Musk seeks to increase the longevity of humanity.
