Not so simple

In Keep it simple, the Economist says:

"LIFE is really simple," said Confucius, "but we insist on making it complicated." The Economist agrees. Unfortunately, Confucius could not have guessed what lay ahead. The rate at which mankind makes life complicated seems ever to accelerate. This is a bad thing.

I've found that quote all over the internet, but it doesn't seem very Confucian to me, and I can't find it online in The Sayings of Confucius, nor in The Analects nor in The Analects of Confucius, nor in Charles Muller's version. Maybe it's supposed to be 剛 、 毅 、 木 、 訥 、 近 仁 ’ ("The firm, the enduring, the simple, and the modest are near to virtue.")
