What satiric point might shaw be making in his characterization of doolittle?

That poorest individual endeavored to work to not be poor, but rather Doolittle is "undeserving poor". He needn't bother with ethics since he can't manage the cost of them and he doesn't need to be great and he wouldn't like to be. 
Doolittle is affronted that Higgins supposes he would offer his little girl for prostitution, he would ask considerably more cash at that point, similar to fifty pounds. He requests his rights as a father and afterward requests more cash
