Democracy and Sense questions practically all that happens in society today. Its aim is to raise a debate on the most urgent problems of economy, democracy, sustainable conduct and the framework for industry and business. A number of untraditional solutions are suggested, but without support to either rightwing or leftwing politics. In fact, one of the key points is that political parties have reduced democracy to one day of voting followed by four years of oligarchy. To regain a functioning democracy we must strengthen direct democracy and make the distance between population and government shorter.

En debatbog der rammer ned i tidens mest vigtige problemer: politikerlede, stigende ulighed, nedgradering af vore omgivelser, og fornemmelsen af afmagt overfor nyliberalismens invasion af samfundets styring. Bogen analyserer hvordan det er kommet hertil og tilbyder adskillige alternativer, nye og gamle der potentielt kan bringe demokratiet til igen at fungere. Vi kan stile mod et mere direkte folkestyre, hvor vejen mellem befolkning og regering er kortere end nu. Et sammenfattende forslag til ny grundlov opstilles, til brug globalt, regionalt eller lokalt, og tilbydes til generel debat.
