How does Bernard Shaw and H.G. Wells relate to mr Birling's speech?

Birling was a capitalist. Wells and Shaw were both socialists, a political stance he found detestable.

birling as we know had a very strict view on capitalism and "how a man has to look after himself", wells and shaw was in fact opposed to birling in the sense of how each parties viwed the society, birling found wells and shaw view as something he'd oppose and something he pretty mush is against, the quote in an inspector calls "we cant let these wells and shaw do the talking we business men have to say something" this quote shows that arthur birling is always against soething hat opposes his course and the reason wells and shaw have been linked with an inspector calls is because J.B. prisetly sees wells and shaw as people who represented his socitical views and it all links with priestly trying to show the audience the positivity of socialism.
