Thank you for the advice Wilf G and JF ZAK, It has truly helped me out a lot and I can't thank you enough

I have attempted to utilise each of your advice for creating my next writing by delving deeper into the analysis, and would really appreciate it if you would take a look at it.
I realise I struggle a lot with expanding my analysis and preventing it from being shallow and literal takes a lot of time which I think will cause me to not be able to write as much in the exam, could I have some advice on how to expand my analysis and tips on what to do if I am really stuck. Is there a sequential method I can use to guarantee good ideas? (this happened on the third paragraph which was why I ended it with "...")
Apologies for not posting the question before Wilf G. The one I used for the essay below is "How does Priestley explore responsibility in An Inspector Calls?"
In An Inspector Calls, Priestley explores the idea of responsibility through the reactions that the Birling family has to Eva Smith’s death: while some of the younger generations are illustrated as being remorseful and feeling “rotten”, other members of the family simply don’t care as it was not their “responsibility”. Priestley could have done this to bring awareness of the archetypal Edwardian attitudes towards the lower class, where the generational divide could perhaps be suggesting that there is salvation: only through socialism.
In An Inspector Calls, Priestley illustrates the middle-class responsibility (and therefore the lack of it) through Mr Birling’s perpetual “hard-headed” attitude, refusing to accept the consequences of his actions. At the start of the play, Mr Birling’s lengthy speech claims that “A man has to mind his own business”, where it could perhaps be representative of Mr Birling lack of regard towards the lower class, seeing them as nothing but “business”. Through the objectification of the lower class, it further typifies his irresponsibility, presenting his belief that those of the lower class are nothing but a means of “lowering prices”. Furthermore, this could perhaps be symbolic of Mr Birlings attitude towards life, where he views life as simply being a “business”, this illustrates Mr Birling attitude towards responsibility as avoidable, simply utilising his superiority to escape it. Not only does he decide to fire the “ring leaders” to avoid his “duty“ as a factory owner, but he also tries to bribe the Inspector, promising “thousands and thousands”. Priestley could have utilised the Inspector as a classless character, unable to be subjected to the restrictions of society and therefore allows for Mr Birling to finally accept his responsibility for his actions. However, Mr Birling’s attitude towards life could alternately be interpreted Priestley could have done this to criticise those of the middle class who abuse their power in their superficial drive for materialistic goods, only willing to give money once they were accountable for their actions.
Furthermore, In An Inspector Calls as the play approaches the end, it become apparent of lack of change within the middle-class attitude towards responsibility; Upon the revelation of the Inspector being nothing but a “hoax”, Mr Birling returns back to his own selfish ways, describing his relief as “We’ve been had, that’s all”. Through the use of the word “been”, the past tense could be representative of Mr Birlings dismissal of his wrongdoings, seeing it as simply being something in the past. Furthermore, this could further highlight his perception of the Inspector as being nothing more than a joke or a “hoax”, drawing a parallelism to a magic trick, which highlights Mr Birlings perceived insignificance of the lower class, being nothing more than a form of light entertainment or revelation. Priestley could have used the monosyllabic words to highlight a deeper issue within society, perhaps in an attempt to portray Mr Birlings shallow perception of his own wrongdoing as being instilled by society, forced upon him by the expectations of the upper class since his birth. Mr Birling unable to free himself from the restrictions of society, is simply just going to repeat his actions and therefore works as a criticism of Capitalism.
However, In An Inspector Calls, Priestley illustrates the changing attitude towards responsibility within the middle-class society through the younger generation. Sheila is initially presented as a naïve and dependant person who changes from a selfish and naïve character, evolving later into one who is willing to claim responsibility for her actions. After the Inspector leaves, Sheila claims that “between us we drove that girl to suicide”, this could have represented Sheila’s acknowledgement of her own wrongdoing, even going so far as to illustrate her acceptance of the consequences of those around her. Furthermore, through the constant repetition of the plural words “we” and “us” it could highlight the contrast between the younger generation and the older one, where instead of shifting the blame to others, Sheila instead fully accepts it….
In conclusion, Priestley has presented a drastic change the younger generation has had towards their attitude of responsibility, while the older generation is seen as static and stubborn in their attitudes. This highlights Priestley’s message of how Capitalism will keep society confined and perpetuated in agony as those of the middle class are unable to learn responsibility, yet Socialism will provide salvation as it will free the Edwardian society from their rigid attitudes towards responsibility.
