Who Was Most Responsible for Eva Smith's Death?

Who was most responsible for Eva Smith's death?

Everyone in this play has been associated individually with her death. She committed suicide which was the build up of chaos and continuous stress that could have also taken a part to drive her to her death.
An Inspector calls is simply about an inspector who calls upon the Birling family to ask about Eva Smith's death.
I think there are three main people who are to blame for her suicide overall.
Mr. Birling is the first person who is responsible; he fired her from his company, as she started a strike about higher wages. She was in the head group of girls and was the cause of the strike. She, as well as many other younger women, wanted average 25 wages instead of 22-26. She needed the money as we can see and I think it was very harsh to permantely remove her, especially when Mr. Birling even admitted that Eva was one of his finest workers. There could be other ways to sort the strike out instead of sacking her.
Sheila Birling was the next person who is equally responsible; she went to Milwards to try on a dress which she liked very much. After Eva was sacked, she got herself a job at Milwards; this is when she met Sheila. Eva smirked at Sheila, whilst she was trying the same dress on as Eva. Sheila instantly got annoyed and acted by talking to the manager and complaining about Eva.
