It's my guess that something like 5% of GDP goes to money management and itsattendant friction. I define it broadly - annuities, incentive pay, all trading, etc. Nobody else has used figures that high, but that's my guess. Worst of all, the people doing this are among the best and the brightest. Hundreds and thousands of engineers, etc. are going into hedge funds and investment banking. That is not an intelligent allocation of the brainpower of the civilization.
In short, the early receivers of the new money in this market chain of events gain at the expense of those who receive the money toward the end of the chain, and still worse losers are the people (e.g., those on fixed incomes such as annuities, interest, or pensions) who never receive the new money.
The first people to get the new money are the counterfeiters, which they use to buy various goods and services. The second receivers of the new money are the retailers who sell those goods to the counterfeiters. And on and on the new money ripples out through the system, going from one pocket or till to another. As it does so, there is an immediate redistribution effect. For first the counterfeiters, then the retailers, etc. have new money and monetary income they use to bid up goods and services, increasing their demand and raising the prices of the goods that they purchase. But as prices of goods begin to rise in response to the higher quantity of money, those who haven't yet received the new money find the prices of the goods they buy have gone up, while their own selling prices or incomes have not risen. In short, the early receivers of the new money in this market chain of events gain at the expense of those who receive the money toward the end of the chain, and still worse losers are the people (e.g., those on fixed incomes such as annuities, interest, or pensions) who never receive the new money at all.
