How far should redistribution go? Who should pay for it and how? What is the proper role of the State and what is better left to private initiative? Should insolvent banks be bailed-out? Is it better to tax individuals when they consume or as soon as they earn their income? Should we rely on taxation to bent individuals’ behaviour towards a cleaner, safer life (sin taxes and fat taxes)? Every one has—or should have—an opinion on those important questions.
