Is the Inspector the only one who has socialist views in the play?

Besides the Inspector, the younger generation in the play display socialistic attitudes and hold such ideologies. Gerald is exempt from this as he, being the son of Lord Croft, is a man of business. Eric and Sheila are young and naive and still don't have any idea what the real world is like - having led a spoilt and shielded life. They are outraged and are in disbelief when they first discover that Arthur Birling dismissed 'Eva Smith' from his works - despite Birling explaining his situation and his reasons. At Milwards, Sheila displays her inner child - resulting in a member of staff losing their job. She has no real concept of the repercussions of one's actions and so is considered to be a hypocrite when criticising other members of her family and Gerald. She thinks herself to be more 'grown up' than she really is, and, this results in 'Eva' losing her last steady job before her death. Eric shares Sheila's views and also thinks he knows how business works. The audience know this to not be the case, however, as they discover that Arthur Birling held Eric on a low-end role in the works. He also criticises and tries to shift the blame to the other characters, but ultimately he is the reason that 'Eva's' child died before it was born as well as the reason that Eva was driven to the point where she felt she had to go to Eric's mother's charity to ask for help. Note, she has to go to his mother instead of him. What does this say about Eric, you ask? It is the final piece of evidence needed in presenting him as what I have described. Because he was so naive and led such a spoilt and shielded life, he was unable to assist 'Eva' with financial support and, frankly, didn't even love her - using her only for his pleasure. Given, this is something some adults do - however they are usually aware that there can be implications of these kind of relationships. Eric is the binary opposite. A lost child who only has himself in mind. He doesn't care - perhaps another of Priestley's subtle criticisms of the upper class and the effect it has upon the upbrining of children.
