The supermarket is full of so-called “anti-aging” creams. This past summer, two workers from a social health center in Terrassa filmed themselves harassing a resident: they called her “old curmudgeon.” 55% of young Europeans between the ages of 15 and 24 say they feel unfairly treated because of their age. In 2020, the hashtag #BoomerRemover was spread on Twitter with an offensive insinuation about how COVID-19 strikes more seriously in the elderly. A study in Canada has shown what many young people of emancipation age already knew: the mistrust of landlords makes it more difficult for them to rent a flat. The background of these examples is called ageism, a dynamic of discrimination based on assigning people attributes according to their age, which produces situations of injustice and disadvantage before other people.
