1.Why didn't the workers succeed in creating the worker's utopia?

There are a number of reasons why the Marxist workers' utopia did not come to life. First of all, not everyone in the working class supported the notion of uniting against the “evil” capitalists. Many saw wage labor as an opportunity for advancement and prosperity. Also, aside from the poor workers, many others had accumulated considerable wealth that they would not readily be willing to give up. This was one of the reasons why the communist revolution in Russia took so many lives. Since there were many differences in income among workers from the start, the workers earning more were not willing to level off with everyone else. It is simply irrational to expect that everyone would support the same idea, especially with preexisting income differences. Also, most people are somewhat afraid of change, and thus it is logical to assume that people simply would not be willing to give up their somewhat stable lifestyles for some bleak and uncertain benefit.
Further along the way, after the world war 2, the idea of the worker's utopia started vanishing in the light of newly emerging capitalist countries. In comparison of the capitalist riches and opportunities to the poverty and degradation in communist states, the Marxist ideas of worker's class communes have lost their appeal. Hence, we may never know what this kind of life would look like, since the worker's utopia never actually took on its intended form and remains just an utopia.
