Rich Dad, Poor Dad: What The Rich Teach Their Kids About Money—That The Poor And The Middle Class Do Not!, by Robert T. Kiyosaki, compares the financial philosophies of the author's two fathers: his biological father—the poor dad—and the father of his childhood best friend, Mike—the rich dad.

Throughout the book, the author compares both fathers, and how his real father, the poor and struggling but highly educated man, paled against his rich dad in terms of asset building and business acumen.
