Err.... OK... The Guardian article that you responded to was not giving you a caricature of working peoples' diets and food preferences.
It was showing how Trump imposed his own cheapness and love of junk food on a visiting group of athletes.
The target was Trump not your creation of 'working class scum' as a subject of elite and 'sneering' Guardian journalists.
There is plenty wrong with the Guardian - from its Blairism to its affluent London-centric view of the world - but in this case you have just confused yourself and blown your own toes off!
At least if (as I originally thought) you were just coming in with more Trump myth-making you might have made some sense - whilst being 100% wrong. But it seems you were further off the rails than that.
