How are industrialism and self-discovery (science and religion) during the Victorian Era revealed in The Importance of Being Earnest?

Industrialization led to the dissemination of wealth beyond the hereditary land-owning nobility. This gave rise to social anxiety, with increased efforts to use manners and cultural capital to define class in order to make the class system less permeable—something we can see in Lady Bracknell's interrogation of Jack and Gwendolen's replication of her snobbery on her initial dialogue with Cecily.
Industry is also represented via the railroads, which enable fast and convenient circulation of characters from city to country. Also, in this period, railroads and nearby shops (railroad stalls) were often implicated in the rise of a certain class of popular sensationalistic genre fiction, often written by women, and printed in small-format, inexpensive books which could easily be purchased and carried on rail journeys, something reflected in Prism's novel.
Religion and self-discovery are both parodied in the name changes that occur in the country episodes. Religion is treated more in terms of the bureaucracy of the Church of England—its involvement in issues such as registration of births, names, and marriages—than as a form of spirituality.
