John Bussey:

Just half in U.S. view capitalism positively, even fewer can define it. But the election will be a referendum on it. http://on.wsj.com/MJKDbs

The fact that so many can't define it is a sign of the system's success. If you don't know what capitalism is, you won't be able to mentally separate it from reality. If you can't separate it from reality, you will not see it as what it truly is, historical, but as what it is truly not, natural. If see it as natural, will be incapable of imagining other alternatives, other forms of social relations, other possible worlds.
