earning money is the hardest way to get rich because it means you have to work, and you usually have to work hard or be especially talented or lucky or both. People who work regular jobs, such as taxi drivers, do not get rich, even they save all of their money. That is because they do not make enough money during their lifetimes to be able to save enough. They may have more money than their friends and co-workers, but they are not really rich.
A few rich men and women have earned their money by inventing some thing unusual or popular or by taking chances and being lucky. Sam Walton was one of the richest men in the United States.
