For a revolution you need a revolutionary situation in a society, Lenin described two conditions "The bottoms don't want and the tops cannot live in the old way".

It is often connected to food or another word necessity's. That was the case during the "arab spring" and was also the case in 1917 Russia, the main slogan for the Russian revolution being "bread and peace". The Russian people had nothing left to lose and the ruling class had nothing left to give(to sustain their power) thus fulfilling the two conditions.

All you need then is a catalyst. Which in the case of the "arab spring" was when Mohamed Bouazizi set him self on fire.

When it concerns America and mass-surveillance I would see that as a possible catalyst that lacked a revolutionary situation.
