The reason this is not readily apparent to people today is that capitalism operates on the principle of individual competition for private property. This means that under capitalism there is the contradiction of industrial production being social and cooperative in nature, while the distribution of the proceeds of production is decided through the competitive struggle of individuals, each looking out for number one. The question then is whether it is possible for people to cooperate for their own mutual benefit and under their own direction, rather than for the benefit and under the direction of bosses. This is not a matter of whether or not people can be made perfect. Human behavior will always be distorted by misinformed opinions and irrational passions.
Mistakes are inevitable in human affairs.
The realistic goal is to create a system of government that reflects the already existing economic reality of labor cooperation, so that all people can benefit from the wealth they have produced. Of course, mistakes will be made. But when the government has been designed to empower the people to cooperatively manage the workplaces, mistakes can be corrected. They will be corrected because people will have a common interest to do so, unlike the present system where the fact of competing economic interests paralyzes government action. In these social revolutions, people discover by force of circumstances, that they are capable of things previously thought unattainable due to the presumed imperfectibility of humankind.
