Question

the same stereotypes and misgivings about the lower classes still remained

Accepted Answer

This is what Priestley tries
to tackle with his play. Britain had changed on the outside, but many of its feelings and attitudes
were preserved from pre-War times. The upper classes, particularly those from noble families,
believed they were still superior to their lower class counterparts. The country was still divided in
many ways, but these divides were ignored. It’s possible Priestley thought that ignoring these
prejudices was naive and harmful, so he used his play to demonstrate exactly how important it is to
eliminate all class divides in Britain.
