If there's one thing this book doesn't do, is promise you absolutely that you will be rich. Instead, it motivates you to try and look at life, your career, and how you spend and manage money a little differently. However, a real financial education - courses you could take at a community college that teach you how to manage risk, understand investing, real estate, etc etc are ultimately necessary for success.
Interesting anecdotes and stories abound, and honestly they're the best teaching tools used, regardless of their truthiness. You'll learn how to manage money, how corporations work, and why owning a home could be the worst decision you ever make. However, there are a few stumbling blocks that really limit the usefulness of this book:
1. He doesn't full discuss how corporations - and their alternatives - work in detail. He also says that corporations can be used as tax shelters. That's not primarily why corporations exist. They exist to limit the liability of the investors. The major disadvantage with corporations is that earnings are actually taxed twice - once when the earnings are calculated, and again when the investors are paid out. You could also say that they're taxed again when you buy something (sales tax) or when you buy property/investments with the money gained. The point is, corporations are not some magic formula that allow people to keep money that the government would otherwise take away.
2. Risk is vastly understated with many investments. He does a good job of trying to slap sense into how people incorrectly view the stock market - by likening dips in stock prices to a sale at a supermarket for toilet paper (as in, that's time to buy), but doesn't explain how securities investment should be done, or even how to evaluate risk. It basically boils down to "if you like the stock, put a ton of money into it and hope to god it does well". He also advises you to use insider information when buying and selling stock, something that readers might not be aware as being illegal.
3. He acts like having a job is some sort of curse, and people who have jobs can never save money or move further in life. Yet, he prides himself on being one of Xerox's top 5 sales people. Apparently everyone should just quit their job or at least direct their attention to something else despite the fact that the earnings from his jobs are what allowed him to make investments in the first place.
Despite how limited and vague the discussion is, it does put a new spin on looking at things. For example, when you start working, he motivates you to direct your income not on spending and consuming things, but investing that money in assets that will generate you money. This cycle of earning money, reinvesting it, and then reaping earnings is how people indeed get rich. However, you don't necessarily need to invest in businesses or real estate to do this. Mutual funds or even a basic savings account are considered assets that generate revenue for the owners. Furthermore, he advocates using money generated from assets - like rental income from a real estate holding - to buy luxuries, not income that comes from your job. This gives your money momentum - i.e. the car payment for a shiny mercedes doesn't come from your paycheck, it comes from an investment.
However, a dark side to this is that many people tend to overindulge in what's known as "found money" - money that didn't come as a direct byproduct of work. Really, money that comes from an investment should be used for reinvestment and saving. Justifying luxury spending on the path to financial security simply because the source of the money is different isn't necessarily wise financial planning.
This book stresses the importance of financial literacy and how the reason people are poor is because they don't understand how money works. However, this book is only the starting point for a good financial education. Going out and getting one is the next step if you truly want to be successful.
