Billionaires had a great thing going. The ruling in the 2010 Citizens United case, among others, invited the super rich to exert all the influence on policy and politics that their money could buy — and then enjoy all the wealth that influence secured for them in return. Thanks to ever-more-obliging tax policies, the billionaire class grew absurdly rich over the years that followed. In the last five years alone, the wealthiest 20 Americans increased their net worth from $1.3 trillion to $3 trillion, Forbes reported.
And they did it in many cases without the rest of us even having a clue. It took the investigative reporter Jane Mayer five years of relentless digging to figure out how the Koch brothers gained a chokehold on the Republican Party. The title of her 2016 book, “Dark Money,” became synonymous with a particularly effective form of influence that was all but untraceable. The billionaires could have kept on like that forever. All they had to do was keep their mouths closed.
