Protestors demand "social justice." I hate their chant, writes John Stossel. If I oppose their cause, then I'm for social "injustice"? Nonsense. The protesters usually want to punish capitalism. "Spread those resources," says Hillary Clinton. Even capitalists often make the mistake of talking about "social justice" as if it's the opposite of free markets or a reason to rein in markets with more regulations or redistribution of wealth. But there's nothing "just" about the leftist protesters' claimed solution: more big government.
