What is the best way to describe the theme of "Pygmalion"?

In Pygmalion we see that the girl Eliza is treated badly from both the note taker and the other dude (i forgot his name). They are both high class, and the other dude treats Eliza badly like trash and the note taker treats her like a specimen and this is all because of her class born lower class.

*in my opinion

The play, Pygmalion, by Bernard Shaw is about a phonetics expert who makes a bet that he can pass a Cockney flower girl as a duchess in the matter of a few months. This girl, Eliza does achieve the transformation, but at the expense of a familiar life in the gutters, and risks being caste off into the world with nowhere to turn. This play explores many themes, has extensive use of symbolism, interesting tonality, irony, and the play itself is an allusion to ancient Greek mythology.

The major theme in Pygmalion is class. In Britain you are very much judged by your social class. Your class is marked by your clothing, your mannerisms, and your accent.
