I'm totally with you. It's not just about your ethnicity or rich dad, its also your motivation. Some want to be creative, some want to help others and some want to be business people. I know a brilliant artist who has struggled for years to bring in a modest income and there's another artist (mediocre at best) who just happens to have found a niche and is business oriented.
It's OK to be a business person and be successful but you could be the best carer in the world and still be on minimum wage and struggle to live. It would be easy to be bitter but capitalism, (in my case the UK schooling system) and the puritan work ethic have much to answer for.
