We elect representatives to do the great bulk of our politicking for us because we have more important things to do. We have families to raise and jobs to work and homes to maintain. We have our own areas of interest and expertise, our own relationships to cultivate. And, crucially, we have limited time, energy, and mental space. Some of us may choose to make politics our hobby or occupation, but all of us should not have to make that choice.
Politics is one aspect of our society. It is one part of many. We all no more need to be politicos, amateur or professional, than we all need to be philosophers or writers or tailors or dog rescuers or plumbers. Philosophy, books, clothes, rescue dogs, and working toilets are all important, just as politics is, but they are not everyone’s concern all the time. They are some people’s profession and the hobbies of others, but for most of us, these and any other field of work or pastime are only occasionally encountered.
