Whether the majority of the rich made their money or inherited it depends on what you define as 'rich'. The majority of people with 1-10 million dollars built it up over 20 years or more, usually by running a small business. They're in the top 1%...but not the top .001%. Each order of magnitude you go up is an entirely different ballgame and the odds that you made your money in just your own lifetime go down.
