dickens had a complicated relationship with his own family
as a child, dickens was forced to live apart from his parents and work in a warehouse while his father was in prison, which made him deeply ashamed
when his father was released, dickens' mother argued that he should be sent back to work in the warehouse anyway
dickens' feelings of neglect and rejection by his parents may have influenced the scenes of young scrooge alone at school in a christmas carol
as an adult, dickens raised a large family of his own and in 1843, when a christmas carol was released, he already had 4 children and his wife was pregnant with a fifth (they eventually had ten children, which was not uncommon at the time)
he constantly struggled for money to support his family
in a christmas carol, dickens presents an idealised and sentimental view of family in which love and companionship are more important than wealth
in real life, though, dickens was disappointed in almost all of his children and annoyed by the financial burden they caused him throughout his life
