Why do so many of America’s wealthy elite seem hell-bent to foment a revolution? After all, the world’s plutocrats agreed at their annual confab in Davos last month that the big tail risk for Western economies is social unrest, spurred by rising financial inequality. The tail becomes fatter when One Percenters like AOL boss Tim Armstrong, realty mogul Sam Zell and venture capitalist Tom Perkins go pick fights with the little guy.

Armstrong stoked the fires of class conflict last week during his justification of the internet company’s planned reduction in employee retirement benefits. He talked up the company’s generous healthcare benefits, referring to the “million dollars each” paid for the care of two AOL employees’ “distressed babies.”

Armstrong sounded nosy and penny-pinching about healthcare, not to mention cheap about pensions. After a public outcry, including the hot breath of rebellion from the readers of AOL’s own Huffington Post, he expressed regret. A few days later, the company backtracked on the benefits cut. But the damage was done.

Sadly, Armstrong has plenty of company. Chicago property developer Zell, whose wealth Forbes puts at $4 billion, told Bloomberg Television last week that “the 1 percent work harder. The 1 percent are much bigger factors in all forms of our society.” It is hard to sound more self-satisfied.

Moreover, Zell thought he was helping Perkins, who had taken the “like-the-Nazis” meme to a new low. In a January letter to the Wall Street Journal, he compared complaints about gentrification in San Francisco to the persecution of Jews. Even after provoking widespread scorn for his comments, Perkins keeps digging, saying last night: “Some of the Jews were extremely wealthy. I think the parallel holds.”

It sounds like Armstrong, Zell and Perkins skipped Davos this year. Other members of the elite, who did pick up on the gathering concern about the unwashed and underemployed, would be wise to explain the risks to their arrogant brethren.

Though the French Revolution preceded the invention of the Gini Coefficient by more than a century, it was essentially a conflict over the division of economic spoils. The outsized share claimed by callous monarchs, aristocrats and clerics became too much for the citizenry to bear. The lesson from that revolution is still clear today: the inflammation of class distinctions is never good for business.
