What is Collins' real motivation in visiting Longbourne? how does he hope to make amends for the unfortunate financial effects of the entail on the Bennet family?

Mr. Collins' upbringing by an "illiterate and miserly father" along with his unexpected good fortune in finding a patroness like Lady Catherine has led to his lack of good sense and his strange combination of obsequiousness and self-conceit. Now that he is settled he wants to "make amends" for inheriting the Longbourn estate by marrying one of the young ladies in the Bennet household. After meeting them, he was first attracted to Jane because of her beauty, but after hearing from Mrs. Bennet that Jane may soon be engaged, he switches his affections to Elizabeth.
