He also argues that there are great incentives against revolution in societies when people possess things they could lose in a revolution (his main example is property). I think an example of this is May 68's failure to bring political change due to the Communist Party's nonviolent stance/cooperation with the Gaullists. We can debate back and forth why they took an antirevolutionary position but consensus seems to be that they at least did not want to surrender what political power they had won through elections.
He also makes other predictions about how equality in social conditions causes people to be more individualistic and less communal, but at the same time less unique. Again, I think we can witness this first hand in America. Maybe he's wrong about other claims, but I wouldn't say this essay is wrong based on the title alone, since the actual essay reads spot on.
