Why does this chamber still exist?

I honestly just don't get it. I think at this point all of us are aware that communists are simply trying to solve the same problems capitalism causes, but end up causing worse problems. Why not just fix the problems with capitalism and leave it be? Why the need to create some sort of revolution and bring in an entirely new ideology, which has been proven time and time again to be a failure?? I just don't get it. If you're gonna try to argue with me, I'm just gonna block you because I refuse to waste my time arguing with people on the internet.
