What you need is political parties speaking to people in ordinary everyday language that ordinary everyday people can readily understand and relate to. Not everyone is an intellectual, and the possessor of not one but in some cases several degrees, and numerous life experiences in intellectual pursuits, in fact most people aren't! Some of us left education with three or four not very good O'levels and one scraped A'level, some left with little or nothing at all! Talking endlessly about GDP, statistics, and ratio's is talking over a lot of people's heads including mine, leaving a lot us bewildered and frankly bored and turned off. People want to be able to relate their own circumstances with what they are being told in language they can easily understand and feel enthusiastic, (or not) about. In other words politicians need to learn to inspire a crowd, which of course, like him or not, Jeremy Corbyn is successfully doing!
