Yeah, that does sound frustrating. But the way I see it, if voting didn't actually do anything, they wouldn't be spending so much time trying to take away our rights.
We ain’t voting our way out of this one.
So the thing is, this is partially true. We need major systemic change that only direct action such as large scale economic disruptions/protests/boycotts/strikes etc have been able to cause in the past. Almost every concession politicians have made in the past few hundred years towards promoting democratic representation was a direct result of workers holding back the labor that companies rely upon. That is partially why they are trying so hard to automate the economy through AI, it would limit our ability to participate in these disruptions.
(And there is a larger conversation to be had about the lack of community support and resources that other developed nations around the world have in place which allows their workers to go on strike etc and make essential demands without risking starvation or homelessness. That is also why there is so much effort to criminalize aid such as providing food and water to the poor and why wages are kept artificially low.)
But the thing is, voting doesn't do nothing. Especially at the local and state level, voting can have significant impacts on the affordability and livability of your current situation. True the national elections are pretty bullstuff until we do away with the electoral college, but at a state level, the right representative can make the difference between funding your local city's infrastructure repair versus investing in Flock AI tracking to sell your biometrics and behaviour patterns to private corporations.
