The kindest thing to be said about the political theatre of our day is that it is based on a total lack of observation. There are many things wrong with this country, but if you go around saying that politics is entirely rotten, education is entirely rotten, the Royal Family is entirely rotten, marriage is entirely rotten, art is entirely rotten, human beings are entirely rotten, and for good measure that the balance of payments is entirely rotten, the majority of the population, not being committed playwrights, will notice that it isn’t true.
