“It matters because the term fast food hints at a lazy, feckless attitude – people who just can’t be bothered to source or prepare their own food, or even wait for it: people who don’t care what they put into their bodies, or their children’s bodies, so long as it can be done briskly.
Fast food denotes automatic judgment and stereotyping of the consumers – it becomes their fault for choosing fast over quality. By contrast, cheap food tells a fuller (fairer) story and one that at least acknowledges a harsh economic truth – this type of food (fast, junk, but above all cheap) could be all that broke, harassed people can afford.”
What do you think?
Well, I would say that Frank's response to your OP confirms that the term lends itself to a fair amount of prejudice.
Didn't read the link but your quote, is untrue.
A typical fat food product like a big mac contains 90 gr meat. Supermarket value is €0,90. A bun can be had for say €0,25, A slice of Cheese, €0,30,
a pickle, slice of tomato..... say altoghether another €0,35. The price to make it yourself ( but considerably better!) is €1,80 where MacDo sells it for € 3,75
Laziness, convenience and lack of interest & knowledge is what drives fast food succes and certainly not 'it's all they can afford'
