What does Scrooge believe should be confined to prisons and workhouses?

Its not what but Who. Scrooge is told that the poor are in desperate need of some small donation, some food, drink and warmth at that time of year. Scrooges ignorance was such that he belied that being poor , unable to find work because there was none available and what was available was slave labour poorly paid and limited was criminal and therefore they should go to the workhouse which was as bad as prison ro to prison all because there was no work and there fore people were going to suffer. There was no governmental help i.e financial payments at that time - No work no money starve and become homeless
