Rags to riches is roughly 0.001% — aim for incremental improvement
Asked whether ordinary people can change their lot in life, Bright calls the question upsetting and answers honestly: most people are not going to go from rags to riches. She estimates it at around 0.001% and says it rests on luck and on factors people cannot control — if you are born into a village or a desert, no amount of hard work makes rain fall to end the drought killing your animals. What she does believe in is focusing on the small controllable things that make life a bit easier. Most people will see minor incremental improvements in a lifetime, and she is explicit that her own financial advice will not make anyone a millionaire.
“This is really hard and also a quite an upsetting question cuz I actually really don't think most people are going to go from rags…”
“But most people aren't going to go from rags to riches. They might just have minor incremental improvements in their lifetime.”
