I think he brings up many great points that we already float around on here (don't be sectarian, ultra, or anti-AES) but there's one point he emphasizes that there needs to be "a theory" for us to follow.
When I try to think of what our Communist vision of the future in America, and our actual ideas of a program, I come up short. There are for sure many things we call for in terms of reform now with m4a, electoral reform etc. Yet in terms of what our objectives are in the long-term we're all very vague. Of course it's hard to map out what exactly the future brings, but we should also try to create at least an outline of what we will do.
For example, there's the idea of ending the periphery-core relationship in agriculture (America dumps GMO corn etc. made in unsustainable industrial agriculture into the US at extremely low prices into a country, where the farmers now have to produce and sell cash crops instead of food to maybe stay out of debt.) We won't simply be able to snap our fingers to end said relationship, there needs to be a plan of how to end the dumping of commodity crops into the third world without also generating a food crisis in the countries that are currently leashed into it. Stuff like this isn't necessarily fun and epic, but we have to really think about and create plans for these problems if we're to ever succeed.
This was a great talk, it was very inspiring. I watched it a while ago and it helped convinced me that communism, the idea and the struggle, didn't permanently die in 1991, that it's possible to have a communism for the 21st century, one that doesn't wholly reject past efforts, but doesn't nostalgize it either.
