One thing I have seen over and over again in life is that there is virtually no correlation between intelligence and common sense. IQ doesn't seem to translate that way.
People without homes will not quarrel with their leaders. This is well known among our principle men now engaged in forming an imperialism of capitalism to govern the world. By dividing the people we can get them to expend their energies in fighting over questions of no importance to us except as teachers of the common herd.
