I'm confused

So far, I've heard that accumulation, technological advancement, and thus concentration of capital from the previous capitalist economy would leave its print on the later modern socialist economies

But other than that, I've realized I've never looked much into what distinguishes AES's economic management, mainly of state-owned enterprises, from capitalist economy's management, in concrete policy

I can understand co-operatives, but such orgs don't necessarily make up socialism, as you guys would say
