I'm not actually upset Grandma and Grandpa are getting vaccinated first. My state abandoned any pretense that "essential workers" might get prioritized in the vaccine rollout once hospital staff all got theirs and is now functioning on a purely age based rollout. Many of my coworkers and I are "essential" frontline workers and many of us are in our twenties or teens which means we will be some of the last people to get vaccinated, meanwhile a bunch of comfy PMC-types in their thirties and forties who get to work from home are going to get their shots months ahead of us.
It's bad enough that they've essentially condemned us to death for the economy this whole time, but now they're not even doing it for the economy.
It is frustrating but more of them have died so it makes sense. However it does still ring of the sentiment of "cannibalizing the young" that has been emblematic of the Neoliberal period of history. You are entitled to your feeling that this is "more of the same shit" that you've been dealing with your entire life. It is accidentally the correct thing to do this time, but hey, it's alright to be frustrated by it.
