What does Mr Birling think of people in the lower class?

Mr. Birling is the owner of Birling and Company, some sort of factory business which employs several girls to work on (presumably sewing) machines. He is a Magistrate and, two years ago, was Lord Mayor of Brumley. He thus is a man of some standing in the town. He describes himself as a "hard-headed practical man of business," and he is firmly capitalist, even right-wing, in his political views. He looks down on the working class and poor. He exploits them in his business.
