How does Mr.Birling represent the values and ideas of the upper class that J.B. Priestley guards against

Mr. Birling is the owner of Birling and Company, a garmet company. 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 has little empathy for poor people and considers his wealth to be a sign of his superiority to others.

Hello

Mr Birling sees Eva as just one of “several hundred young women” who worked at his factory. This shows that in his view, all of his workers have no value. By saying “they keep changing” he shows the audience he did not even care if he dismissed Eva as she was just cheap labour to him. Therefore, by the victim of the play being a working class female, Priestley highlights the vulnerability of the working class in those times, something that was socially acceptable. This idea also links to the play's theme of gender differences.
