On any TV show, and in the media in general, there are a few different competition formats (a la Bake Off, The Apprentice, BGT, etc.) but all include a 'sob story' element, particularly near the end as we get to know more about the contestants. Every single person selected by the producers for these shows has some factor in their life that they've overcome to get this far.
Individually, this makes for an engaging TV show, we warm to the characters because they have a good story, but overall the effect is damaging, I think. The effect is to create a system that only allows people to feel successful if they've overcome some terrible adversity. It's not enough to come from a comfortable, middle class background, do well in school and then lead a moderately successful life. What have you really achieved if you've done this?
Most people in the UK live reasonably comfortable, stable lives (modulo class). Since—according to my theory—people need to feel like they have something to overcome in order to be allowed to feel successful, people will overstate hardships, and focus on and amplify negative events and circumstances in their lives in order to feel validated.
