The nation’s growing income inequality recently has generated considerable attention—and has sparked a backlash by billionaires. TED’s Chris Anderson showed what a hot button issue it is when he tried to repress a video talk on the subject by venture capitalist Nick Hanauer. Hanauer, like billionaire investor Warren Buffett, supports increasing taxes on corporations and wealthy individuals for the good of the nation. Buffett and other billionaires have joined forces in a new pro-tax-increase-for-the-rich organization to assert: “We are the 1 percent, we stand with the 99 percent.”

Now the issue has hit the presidential campaign trail.

Few would argue that the nation's increasing income inequality is a growing and dangerous concern. But for Chris Anderson, "curator" of the annual TED conference where hip people go to hear innovative talks, income inequality is a "partisan" issue that must not be discussed.
