It’s not that people stopped caring. It’s more that people got fairly comfortable, and the greedy fucks at the top never stopped trying to hoard all of the money and power. So while most people had stopped fighting for better conditions, since conditions got pretty comfortable for a lot of people, the misers were actively working for decades to undermine all of society for their own selfish benefit. After decades of incremental enshitification, it has once again risen to a level where it can no longer be ignored. People have always cared about their own welfare, but they had their QOL slowly stolen while taking a much deserved breather.
