Calling capitalism predatory is redundant. Capitalists seek to maximize the the returns from capital, whatever the means.
I’m not sure if having more employees ownership would solve the predatory nature of capitalism. The employees would still be operating under the economic imperative of capitalism. Institutional investors control 73% of Facebook shares. They can still manipulate stock price to get the company behave in ways they prefer. Many Facebook employees are ultra rich because of the wealth derived from the Facebook shares they own.
As much as I don’t like Facebook, in this article, however, I don’t understand how it’s predatory. Credit card companies prey on their customers’ mistakes, charging them high fees and interest rates. Pharmaceutical corporations prey on the poor by charging them exorbitant drug prices.
