What is the conflict between Higgins and Alfred Doolittle in "Pygmalion"?

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.
