Jelly: first of all, you still seem to be confusing your idea of "communism" with the kind of libertarian socialism that I am espousing. Again, I am opposed to coercive big government and my ideas have nothing in common with the authoritarian regimes of the former Soviet bloc, or any similar regimes. There is nothing "socialist" whatsoever about those states. I’d be happy to direct you to some literature if you are interested in learning more about libertarian socialism / anarchy.
Secondly, what makes you think that a democratic economy (essentially based on worker-owned industry rather than capitalism) cannot work? In 1930s pre-fascist Spain anarchist ideas were very well known and practiced in large parts of that country. They were very successful until they were violently suppressed by the fascists and other parties who were threatened by the emergence of a truly democratic society. In the U.S. in the 19th century, worker-owned cooperatives were so efficient and successful that capitalist industries often could not compete with them. The state had to intervene with subsidies and anti-worker legislation to ensure that the capitalists prevailed over worker-owned industries. Today, although there is admittedly not a lot of empirical research in this area, the available research indicates that worker owned industries are generally more efficient than capitalist owned industries.
In addition to the evidence that an economy based on anarchist / libertarian socialist principles would likely be materially more productive than the present state-supported capitalist economic system, it also seems to be in keeping with the fundamentals of human nature. Human history can be seen as a continual striving towards greater and greater freedom and away from coercive forms of authority. As I alluded to in my initial response to Rex in this threat, the U.S. and other capitalist countries have achieved greater individual civil liberty than in almost any society in human history. But there is clearly still a long way to go. Leaving aside for the moment the recent disturbing reactionary attacks by American governments on fundamental civil rights and liberties, people are still far from free economically. The freedom of most is to restricted to the freedom to attempt to sell their labour to a different capitalist or civil service employer. Either way, the vast majority are not in control of their economic lives – they are working for bosses who are not accountable to them. I believe that human nature will lead people inevitably to demand and obtain greater control over their economic lives just as they have demanded greater and greater control over their political lives. There are solid reasons to believe that capitalism is no more eternal than any system which preceded it. It is riddled with internal contradictions which virtually ensure its’ eventual demise. The overall trend of human history indicates that it will inevitably be replaced by a system which delivers greater freedom, wealth and equality.
