What the fuck are you even on about ? Leave retirees alone. Most of them are living under the poverty line. A handful of them are extremely rich, but that's about it.
There's also literally nothing these people can do about that. It's the government's fault, no one else's. 10 years of policies all aimed to make rich people richer, cutting everything left and right, except the military and corporate handouts.
The kids have rats in the classrooms, literal fucking rats. In the summer they have 40+ degrees in there, and not enough chairs and toilet paper for everyone. It's the same in all our public services and that's just the tip of the iceberg. We have poverty levels higher than 30 years ago, people can't afford to eat, to go to the doctor, to heat their homes.
We riot because our most basic rights are being trampled and fucked with. We tried talking, voting, being peaceful about it, and the only answers we got were disdain, more and more institutional violence, and the goddamn riot police. You should probably learn a thing or two, instead of licking the boot on your neck.
