What enables oppressors to show such unity? Look at mafia, terrorists, smugglers, corrupt politicians, businessmen, imperialists. They all are hand-in-glove when involved in something vile. Somehow, their teams are extremely strong, despite being much smaller than the number of people they oppress. It's got to do with the common urges which drive them to do what they do. Greed, ambition, anger, fear, ego, vanity etc. are very potent motivators and unifiers.
On the other hand, common people never seem to come together? Because most people are cowards. They would rather hide behind their busy life etc. than come out in the open and speak out. They fear unpleasantness and messing it up with the 'important' and 'influential'. They would sometimes even turn against the very people who are trying to stand for them, just to avoid being marked as an agent of change in the existing social order. And agents of change are a set of creatures oppressors hate the most, and go to any length to get them out of their way.
The dominating emotion among the masses is fear. And here's another way fear works: as a paralyser, which is exactly the opposite of how it works on the oppressors.
The oppressors often hold positions of influence, and once in a while do their bit to keep the system going. This could easily be construed as a service to the common man. But it's a delusion. A parasite needs the host to remain alive to be able to suck its blood. An intelligent parasite will go to the extreme of helping its host survive when it's about to die, because if the host dies, the parasite can't survive either. An intelligent parasite will also want to keep its victim deluded that it is actually a helpful guest, who should be allowed to suck its host's blood once in a while as a payback for its services. British, when they were here, also built bridges and buildings, apart from looting the people in immeasurable proportions. And even to this day, we punish ourselves by saying that their coming to our land did us a lot of good, whereas the reality is they kept sucking our lifeblood for two centuries, and left us scarred for centuries to come.
The common man -- lazy, ignorant, fearful -- is happy to lead a subjugated life as long as the oppressors keep them away from the need to understand things and take things in their own hands. They are afraid to take responsibility, to fail, to deal with the discomfort of understanding and learning. When the common man stands up to say something, he cowers back down after seeing the menacing look in the eyes of the oppressor which seems to say: 'Speak, and I will drop everything.'
An oppressor -- a social parasite -- will do everything in his means to keep the masses deluded about the true nature of its relation with the oppressor. One of the most potent ways to do this is to keep the masses divided. Mass ignorance is a great ally of the oppressor. People who are divided can easily be dealt with by a handful of oppressors. When the voices of the people come together, it is a beacon of death for the oppressors. Hence, it's a universal characteristic of the oppressor to try and kill communication. A group of sufferers is a formidable force. A lonely sufferer is puny in comparison. He is so afraid and lacking in confidence that his voice can be silenced for ever with a rap on his knuckles.
I now gradually realise why Netaji and Gandhiji were such great leaders. Because they could make millions of cowards come out on the streets and take up a gun or fill jails. Respect!
