It has long been the case that MPs have been able to have two jobs and lucrative sources of second income, sometimes associated with their Parliamentary responsibilities. One of our best loved leaders, Sir Winston Churchill, wrote several successful books that provided him with extra cash.
It may be argued that MPs' second jobs anchor them in the "real world", forming a connection to the general public that can so easily be lost in the Westminster Village. For example, Sir Paul Beresford has continued to practice as a dentist. The counter argument is that MPs should really be concentrating on politics and their Parliamentary responsibilities, not using their position to make more dosh as nonexecutive directors and the like.
Interactive Democracy feeds everyones' real life experience into the political mix. Every type of democracy needs politicians to be professional and responsible law makers, focused on their jobs as Parliamentarians.
