Revolution will either come, killing most of us, or the train of rampant capitalistic destruction will continue on, killing all of us. We're not close enough to immediate death for most of us to view revolution as an acceptable answer yet, but I have no doubt that in a few decades, when the young adults of that time look back on the current times and think "they had it so easy," the risk associated with an uprising will seem much less daunting when compared to the risk of simply living within whatever jumbled-together scraps of a system we'll have left by then.
Revolution isn't a solution that any sane person gets excited for; it all but guarantees a short life full of suffering for the vast majority of people, but it's a solution that is chosen when the alternative is guaranteed suffering for everyone outside of the upper class. It's the last resort used when the best hope you have for the future is to fight for the chance that a few people make it to peaceful times, because you don't see any other way for anyone to get there by working within the system.
Voting is important, yes; we get the best chance to make it to a revolution by voting blue, slowing down capitalism's destruction of the world, but so long as each election is populated by 2 candidates proudly bought out by corporations who don't give a shit about the world, there will be no viable option within the system to actually stop its destruction. That requires actually changing the system through uprising.
