The novel satirises the shortcomings of both government and society, including the institution of debtors' prisons, where debtors were imprisoned, unable to work, until they repaid their debts. The prison in this case is the Marshalsea, where Dickens’ own father had been imprisoned. Dickens is also critical of the lack of a social safety net, the treatment and safety of industrial workers, as well as the bureaucracy of the British Treasury, in the form of his fictional "Circumlocution Office". In addition, he satirises the stratification of society that results from the British class system.
