I understand what you mean but I do think politicians occupy quite a unique position in society compared to other professions . All professions and professionals can suffer from living within a bubble totally unintentionally . A lot of doctors , engineers , lawyers and others have their world view shaped by their peers and how societies impacts their own , specific bubble . Politicians are no different however their decisions and policies have significant impact in the real world on a number of professions , people and well , everyone really . Having experience of things outside of politics can give you an awareness of how society works across a variety of bubbles and perspectives . All the more powerful if you have a group of politicians made up of a variety of people with different experiences who might be able to use that expertise to focus on policy areas that they themselves have been involved in . This is obviously the ideal situation . If you have a group made up of complete professional politicians then you lose that richness and connection with the real world . You would obviously have a group of people who are skilled at management , negotiation and hopefully communication . However they might be unaware of the true impact of their policy decisions in reality compared to what they thought would happen in theory . To me that doesn ' t totally discount the skills professional politicians can bring to the table , though someone with experience in both worlds would be best . I guess I think political expertise in an a policy area is not a total replacement for real life expertise in that area . But I ' d never claim that as fact ! What ' s your experience of that been as someone in the political world ? Any major differences between how people operate coming from a ' real world ' background vs someone more familiar with how it all operates ?
