Rainer Grunert is author of the book "Visionen einer fairen Wirtschaftsordnung"DW-TV: You write about money, about the economy. So I would like to know your take on the Chiemgauer, that regional currency. Is it actually worth the paper it’s been printed on? Is it just a fad, some socialist romanticism? Rainer Grunert: Well, the Chiemgauer is a very interesting experiment but it is an experiment and not more, because if it becomes too much successful the federal bank of Germany or at least the European bank will stop it.   DW-TV: Because it would harm our national or European currency, the Euro? In what way? Rainer Grunert: It will harm the belief in the currency and as more people mistrust the national currency as more it loses on value. DW-TV: But at the same time like here in Berlin we can't use the Chiemgauer so the harm, if you like, would only be done in the Chiemgau, in that region where you can actually use that regional currency. Rainer Grunert: As long as it stays in this region. But there was an experiment in an Austrian town in the last century where it became very successful and the court in Vienna had to forbid it. DW-TV: OK. So, bottom line: regional currency is a nice idea. It works within a small region for a limited amount of time. So it's short-lived. So there is not really a bigger point to it. Rainer Grunert: There is a bigger point, if it is placed globally. So, for example, if you take the dollar and you combine it with the functions of the regional currency. DW-TV: So that it would actually lose value after a certain amount of time? Rainer Grunert: It loses only value if you store it. Otherwise not. If it's in the flow then it loses no money. DW-TV: That means no more saving money. Nobody can put anything on the safe side. Rainer Grunert: People can put a lot on the safe side. They can buy stocks or similar investments and then they save their investment. But they can no more make money with money only. (Intervi...
