What does Higgins tell his mother is the very thing that fills the “deepest gulf that separates class from class and soul from soul”? Do you agree with him? Why or why not? (Act 3)

From the text:

Playing! The hardest job I ever tackled: make no mistake about that, mother. But you have no idea how frightfully interesting it is to take a human being and change her into a quite different human being by creating a new speech for her. It's filling up the deepest gulf that separates class from class and soul from soul.

I really do not relate to Higgins and his views on class structure and society.
