Hammer them into shape

“A substantial good drawn from a real evil, is of the same benefit to society, as if drawn from a virtue; and where men have not public spirit to render themselves serviceable, it ought to be the study of government to draw the best use possible from their vices. When the governing passion of any man, or set of men, is once known, the method of managing them is easy; for even misers, whom no public virtue can impress, would become generous, could a heavy tax be laid upon covetousness.” – Thomas Paine, “The American Crisis”
