Since unplugging from advertising and learning a lot over the years, I've come to understand that the main reason most people don't have a voice in the affairs of the world is that they don't own the means of production, which for most people means owning shares of companies.
You invest = You get the wealth. You get the wealth = You get control of society.
All these people right now are screaming and shouting about wanting a revolution, but who is actually changing things? Elon Musk is. And that's because he invested intelligently and now he's leveraged those investments to overpower his enemies and fund things like solar power, electric cars, and the Hyperloop. A lot of powerful people want to stop him because these new technologies are going to annihilate entire industries that have allowed them to control our nation, but he just tells them to sit and swivel because he has the cash.
I wish more people would recognize how to truly empower themselves.
