Leaving aside the issue of a potential lack of kitchen appliances, cooking knowledge and skills, implements, access to certain foods, and time, here’s George Orwell’s opinion on why the poor may eat the way they eat, from Wigan Pier:
“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 ! That is how your mind works…. White bread-and-marg and sugared tea don’t nourish you to any extent, but they are nicer (at least most people think so) than brown bread-and-dripping and cold water.”Brown bread-and-dripping, or, lentils of superiority.
