Robert T. Kiyosaki's 'Rich Dad Poor Dad' contrasts the financial philosophies of his two fathers, one wealthy and one poor, emphasizing that the rich teach their children about money while the poor do not. The book outlines essential financial lessons, such as the importance of financial education and how thoughts and beliefs shape one's financial destiny. Kiyosaki advocates for an understanding of money that allows individuals to make it work for them instead of simply working for it.
