Looking only at the illustration by Andrew Dyson and not the article in this link, what is Dyson's contention?
The contention of this illustration is that the Occupy movement has very little chance of success. The reason for this is that there is a huge imbalance in power and resources between it and the system that it is trying to alter. The system is being represented by the man in the suit. We can see that it is powerful and rich because it is so big and so fat compared to the protestor. Its power over the protestor is shown by the fact that he is held firmly in the fist of the large and faceless figure.
