Would it be Ok to take this sentence out completely?
A large home, a gardener, expensive furniture, the best clothes,and jewelry but it isn't enough to satisfy them enough to stop wasting all of the income from Richard's job on the expected position motivates them,which makes it very difficult to have much sympathy for the mother
I just read what you wrote, and my opinion is..
If you remove it, nothing ties the first sentence to the sentence after the above. I think I would rewrite it into a simple sentence (or two). I think it is necessary in your paper to give examples to the first sentence, as that in fact is the situation in the story. The reason this sentence stands out is because it is way to complex, and is difficult to follow.
So, I would keep it in shorter version.
