Never heard of the Milgram experiment? People usually go to extreme lengths before they defy authority.
On the other hand, when revolutions do come, we see a huge upsurge of what I'd have to call "revolutionary spirit," embodied in the form of voluntarism and a united people. You can see this in the ongoing conditions of Egypt, with Christian anti-government protesters protecting the Muslims while they pray, or earlier when people formed a human chain around the national museum to protect it.
Of course there is a lot "revolutionary spirit", this is the moment when the dictators seduce us, tease us and treat us to dinner before they **** us in the ass.
