The fundamental law of revolution, which has been confirmed by all revolutions, is as follows: for a revolution to take place it is not enough for the exploited and oppressed masses to realise the impossibility of living in the old way, and demand changes; for a revolution to take place it is essential that the exploiters should not be able to live and rule in the old way. It is only when the “lower classes” do not want to live in the old way and the “upper classes” cannot carry on in the old way that the revolution can triumph.
—Vladimir Lenin on crisis and revolution
