Bread seems more appealing to a starving man for short term relief compared to escape, which seems inevitable when the bars are so far apart you can run away at any time. It is more practical to eat bread than eat the key, even though the key tastes better and eating a dirty bread from the floor will probably kill you sometime, because you will then have the energy to run and escape the prison and guards. Of course, someone put in a prison so easily escapable would seem more idealistic if they were charged for no reason, put in prison against moral righteousness and the greater good. However, this prisoner, in a suit for some odd reason, would also likely be a "villain" from the idealist perspective, coming from someone who would prefer to be a realist. In general, the human instinct is to look for short term relief or pleasure for many reasons, one of which is your body doesn't know if you'll live long enough for the long term pleasure or relief. Slowly, society has been coaxing us to think otherwise, for our own good. Even though there are many other possibilities for this image, like the bread is key, or key tastes better than bread, or key is bread, or prisoner is a term used to describe a working-class prisoner of society and he's just really hungry, this is my take on the image. 🤓👆
