I would be lying, however, if I claimed that I could always formulate worthwhile hypotheses on the basis of my theoretical framework. Sometimes there were no reflexive processes to be found; sometimes I failed to find them; and, what was the most painful of all, sometimes I got them wrong. One way or another, I often invested without a worthwhile hypothesis and my activities were not very different from a random walk.

In 2012, the far-right Golden Dawn won 21 seats in Greece's parliamentary election, the right-wing Jobbik gained ground in my native Hungary, and the National Front's Marine Le Pen received strong backing in France's presidential election.

A global economy is characterized not only by the free movement of goods and services but, more important, by the free movement of ideas and of capital.
