As is often the case with Ms. Austen's fiction, "Persuasion" deals with the social issues of the times and paints a fascinating portrait of Regency England, especially when dealing with the class system. Rigid social barriers existed - and everyone wanted to marry "up" to a higher station - and, of course, into wealth. This is also a very poignant and passionate story of love, disappointment, loss and redemption. The point Austen makes here, is that one should not ever be persuaded to abandon core values and beliefs, especially for ignoble goals. There are consequences, always.
