The richer character in oliver twist are, on the whole,happier than the poor characters.Is Dickens arguing that money leads to happiness? WHY or WHY NOT ?

Money is only good in Oliver Twist in the hands of characters who do not care about it. The most moral characters in the novel each renounce money in some way, or show generosity with it—Oliver splits his inheritance with the half-brother who tried to destroy him, Harry Maylie chooses the humble life of a country cleric rather than an ambitious life, and Mr. Brownlow and Mrs. Maylie are both very generous with their resources. Poverty is dangerous, not because money leads to happiness but because poverty often leads to desperate attempts to get money, often through immoral means.
