anyway, I still get a distinct notion that you equate socialism and communist. those are not the same. communism was never tried. socialism has. it failed at some places, and it appears to be holding up at others despite sabotage. whereas capitalism... well, not really working well anywhere, is it? exponential accumulation of capital can't possibly work in finite settings.
