“ When you are unemployed, which is to say when you are underfed, harassed, bored and miserable, you don’t want to eat dull wholesome food. ”

“And the peculiar evil is this, that the less money you have, the less inclined you feel to spend it on wholesome food. A millionaire may enjoy breakfasting off orange juice and Ryvita biscuits; an unemployed man doesn’t. Here the tendency of which I spoke at the end of the last chapter comes into play. When you are unemployed, which is to say when you are underfed, harassed, bored and miserable, you don’t want to eat dull wholesome food. You want something a little bit ‘tasty’. There is always some cheaply pleasant thing to tempt you. Let’s have three pennorth of chips! Run out and buy us a twopenny ice-cream! Put the kettle on and we’ll all have a nice cup of tea!” source
