We have this culture of financialization. People think they need to make money with their savings rather with their own business. So you end up with dentists who are more traders than dentists. A dentist should drill teeth and use whatever he does in the stock market for entertainment.
People should have three sources of variation in their income. The first one is their own business that they understand rather well. Focus on that. The second one is their savings. Make sure you preserve them. The third portion is the speculative portion: Whatever you are willing to lose, you can invest in whatever you want.
In the second category—preservation of value—you should have the consciousness that there is something called inflation. You should avoid some classes of investments that are very fragile."
The problem is getting runaway. It's becoming a pure Ponzi scheme. It's very nonlinear: You need more and more debt just to stay where you are. And what broke [convicted financier Bernard] Madoff is going to break governments. They need to find new suckers all the time. And unfortunately the world has run out of suckers."
