Dialectical Materialism. Right now, they are. You either work towards communism or capitalism moves towards consolidation of capital. Those are your choices.
thats not a mix though, it was just a bandaid over capitalism, borrowed from socialistic ideas. the capital accumulating class was never extinguished, eventually leading to the same problems today all over again.
hence why we advocate for a systemic change, if you can't accumulate capital, you can't buy back the system again like it is rn. this is pretty much the crux of the issue here.
