Most Cuban lives actually lie in the hands of something called the Committee for the Defense of the Revolution. This really is thousands of small committees organized down to the block level, like the one meeting above in Havana. The most active members belong to ORI, an organization made up of both Castro supporters and Communists. They know everything in the life of everyone. Yet they also can give- and take away- favors, so most Cubans seem to accept their embrace without ever thinking that it could, in the end, smother them.
