And if you don39。t have a good job, how do you plan to get rich? My son smir ked and slowly shook his head with mild boredom. We have had this talk many times before. He lowered his head and rolled his eyes. My words of motherly wisdom were falling on deaf ears once again. Though smart and stronarranged for both of us to participate in a test of the prototype. Because it was an educational game, I also asked my 19yearold daughter, who was a freshman at a local university, if she would like to take part, and she agreed. About fifteen people, broken into three groups, participated in the test. That happy couple, born 35 years ago, is now trapped in the Rat Race for the rest of their working days. They work for the owners of the We found out we had a lot in mon. We covered the gamut, from sports and plays to restaurants and socioeconomic issues. We talked about the changing world. We spent a lot of time discussing how most Americans have little or nothing saved for retirement, as well as the almost bankrupt state of Social Security and Medic are. Would my children be required to pay for the retirement of 75 million baby boomers? We wondered if people realize how risky it is to depend on a pension plan. Robert39。s primary concern was the growing gap between the haves and have nots, in America and around the w orld. A self taught, selfmade entrepreneur who traveled the world putting investments toge ther, Robert was able to retire at the age of 47. He came out of retirement because he shares the same concern I have for my own children. He knows that the w orld has changed, but education has not changed with it. According to Robert, children spend years in an antiquated educational system, studying subjects they will never use, preparing for a world that no longer exists. Today, the most dangerous advice you can give a child is `Go to school, get good grades and look for a safe secure job,39。 he likes to say. That is old advice, and it39。s bad advice. If you could see what is happening in Asia, Europe, South America, you would be as concerned as I am. It39。s bad advice, he believes, because if you want your child to have a financially secure future, they can39。t play by the old set of rules. It39。s just too risky. I asked him what he meant by old rules? . People like me play by a different set of rules from what you play by, he said. What happens when a corporation announces a downsizing? People get laid off, I said. Families are hurt. Unemployment goes up. Yes, but what happens to the pany, in particular a public pany on the stock exchange? The price of the stoc k usually goes up w hen the downsizing is announced, I said. The market likes it when a pany reduce s its labor costs, either through automation or just consolidating the labor force in general. That39。s right, he said. And when stock prices go up, people like me, the shareholders, get richer. That is what I mean by a different set of rules. Employees lose。 owners and investors win. Robert was describing not only the difference between an employee and employer, but also the difference between controlling y our own destiny and giving up that control to someone else. But it39。s hard for most people to understand why that happens, I said. They just think it39。s not fair. That39。s why it is foolish to simply say to a child, `Get a good education,39。 he said. It is foolish to assume that the educ ation the school system provides will prepare your children for the world they will face upon graduation. Each child needs more education. Different education. And they need to know the rules. The different sets of rules. There are rules of money that the rich play by, and there are the rules that the other 95 percent of the population plays by, he said. A nd the 95 percent learns those rules at home and in school. Tha t is why it39。s risky today to simply say to a child, `Study hard and look for a job.39。 A child today needs a more sophisticated education, and the current sy stem is not delivering the goods. I don39。t care how many puters they put in the classroom or how much money schools spend. How can the education system teach a subject that it doe s not know? So how does a parent teach their children, w hat the school does not? How do you teach accounting to a child? Won39。t they get bored? And how do you teach investing when as a parent you your self are risk averse? Instead of teaching my children to simply play it safe, I decided it was best to teach them to play it smart. So how would you teach a child about money and all the things we39。ve talked about? I asked Robert. How can we make it easy for parents especially when they don39。t understand it themselves? I wrote a book on the subject, he said. Whe
