Basically what the title says. I tend to lean anarchist but I'm not opposed to reading some Soviet sympathetic literature since I like to expand my horizons.
Edit: to be more specific. Parenti describes life in the Soviet Union as largely comfortable, perhaps too comfortable. People's needs are largely met. They have economic security. Most folks are quite skeptical of the news, "I know of all these disasters happening around the world but I don't know anything that's happening in my own country" and a general disbelief in the true news about the problems in capitalist countries. This results in a disatisfaction, particularly among the intelligencia and beauracracy, that results in the top down disollution of the USSR. From there he describes shock therapy and the deprevation that resulted.
How good is his research? How good are his sources? I believe quite strongly that we live in the most sophisticated propoganda machine ever devised. That makes me skeptical of a lot of the common narratives about the USSR but more than just the US is capable of lying and I'm curious how willing Parenti is to believe in obvious falsehood.
It should be noted he does criticize the USSR but at the end of the day believes in the project of state communism.
All of these are individual actions. I'd add organizing with other folks trying to make a difference. Direct action or political advocacy can have a much more significant effect than an individual acting alone.
