Money and the wealthy. Everything I was told to look forward to when I got older was smashed and lit on fire in front of my fucking eyes by people who have never wanted for anything. I'm 40, now. I saw the birth of videogames and the Internet, only to watch it get burned down around me so some nepo-baby with a silver spoon can have another zero in their bank account.
We are one of the only generations to have their life be WORSE OFF than their parents, and it hurts the most because those parents likely participated in, or voted for, the very mechanisms that led here. If I'm ever terminally diagnosed with some illness, you'll see me become the Mario to our modern Luigi.
