Due to rich poor dichotomy can a revolution come?

In India, there is a big gap between the rich and the poor. But this has been present all through history. And poor have lived with this. So a revolution cannot come due to differences( between classes--rich and poor)
In modern age, more changes have come.A middle class has emerged too.There seems to be anger towards this class. This is unreasonable. The middle class struggles to survive as the poor does. And this middle class is the educated class and is aware of changes in political scene.
The poor workers need to ally themselves with this middle class, if they want to be heard.
Recent trend is to tax the educated class(and not the rich capitalist class).And resentment seems to be rising, all have to be pleased.This is predictable.If the political class wants to survive, it must make favorable climate for the educated class.Because without its support, it cannot survive long.
