Initially, it is one of money. Higgins and Doolittle both know that Doolittle only comes to profit off Eliza being there. As Doolittle attempts to dissuade Higgins of this, Higgins begins to like him and offer him more money. The conflict then centers over Doolittle's desire to remain in the poorest class of society. If he is poor, he has no responsibility and no one expects anything of him. Later, this conflict arises again. Doolittle is given money because of Higgins praise. Doolittle is suddenly thrown into the middle class, and now must suffer from "middle class morality." His life of freeloading and wasting is over.
