Kiyosaki had two fathers: one poor and the other rich. He called his biological father poor, not because he lacked money, but because he was an employee and aspired to advance. The rich father was the father of his best friend, Mike. Kiyosaki called Mike's father "Rich Dad" because the man wanted to live richly as a company owner rather than a wage earner. Kiyosaki describes in his book, "Rich Dad Poor Dad", his childhood in the bosom of his biological family and his childhood in the bosom of the family of his friend Mike and his "rich" father.
