Historically society hasn't progressed into a new system, then regressed into the previous system cyclically. Different societies are qualitatively different, not merely different arrangements of quantitative variables that all add up to the same sum; there are certain arrangements that one can regard as better than others. It's true that communism won't be a struggle-less, problem-free utopia, but I regard it as a better arrangement of society and as the next step in historical development after capitalism.
You just said a whole lot of nothing. You say it's better but you never gave a reason why. So... Why?
I wasn't arguing for communism over capitalism; the main issue I took with your post was the stupid ahistorical assumption that communism and capitalism are two sides of the same coin, that the two could ever interchange or revert between eachother. Communist society comes about by the movement to abolish capitalism, a movement generated by the contradictions present within capitalism. If communism isn't the end of history, then what follows it will emerge out of the contradictions present within communist society and generate something qualitatively different both from communist and capialist society.
"Thee main issue I took with your post was the stupid ahistorical assumption that communism and capitalism are two sides of the same coin, that the two could ever interchange or revert between eachother. " Hahaha! Ahistorical, huh? Wanna check how many countries changed to capitalism after the collapse of the Soviet Union? Russia, for example. And while you may argue that the Soviet Union wasn't communist, it seemingly got closer to communism than anything I can think of, which was reeeaaaaallly close.
The USSR was not communist. It was not close to being communist. It was not progressing towards communism. If you think that the USSR was reeeaaallly close to communism, then you have a completely inaaccurate understanding of both the USSR and communism. Only a few minutes reading the Wikipedia articles on communism and the USSR would show how demonstrably false you understanding is. Considering that you are apparantly too lazy to look these things up before bringing them up, I'll help you by posting links below.
