What’s absolutely mind-bending about this line is that there IS a conspiracy of the world’s most profitable trillion-dollar corporations and their paid-off lackeys at the highest levels of government, who for decades knowingly HID THE TRUTH from you to protect their fortunes! It’s… just… well… take a look behind you.

What’s more, this particular industry has a long history of using conspiracies to expand and protect their business and ultimately reshaped the entire country so almost every American is dependent on purchasing and burning their poisonous products every single day: “over the course of several generations lawmakers rewrote the rules of American life to conform to the interests of Big Oil, the auto barons, and the car-loving 1 percenters of the Roaring Twenties.”
How rich and powerful is the fossil fuel industry? Just one example: the entire amount that Americans spent on bicycle sales and service in a full year is equivalent to what Americans spend in less than one day on cars and gasoline.
So if you want to be righteously angry about corporate greed and entrenched elites, start paying attention to the man behind the curtain!
