George Macdonald said this quote

It is a hard thing for a rich man to grow poor; but it is an awful thing for him to grow dishonest, and some kinds of speculation lead a man deep into dishonesty before he thinks what he is about. Poverty will not make a man worthless—he may be of worth a great deal more when he is poor than he was when he was rich; but dishonesty goes very far indeed to make a man of no value—a thing to be thrown out in the dust-hole of the creation, like a bit of broken basin, or dirty rag.
