The difficulty with the issue of staying or leaving the EEC is that very few people know enough real facts in order to make a decision one way of the other. Anyway, it is easily conflated with extraneous matter, like immigration and "bloody foreigners" If you ask people why they want to leave the EEC, they start mumbling incoherently.
Trying to have a serious informed debate on the EEC in Britain today is like trying to nail custard to the wall. Before long, the discussion becomes awash with tired drivel about warm beer, cricket and the Queen Mother.
In Wales where I live, we have seen money coming in for infrastructure projects that Westminster have shown an unwillingness to spend, especially during the 80's and most of the 90's. We have definitely gained from our membership. But wealthier parts of the UK might not have had the same experience.
I am a democrat and I believe that debate is healthy but it has to be informed debate, not a ilinformed slanging match.
