Says the person who believes in race and other pseudoscience. Listen, this thread is about the development of a utopian future in the vein of Star Trek and other forward looking social systems. While we are talking about the future, you are reaching back to 1833 for ideas? Really Jim?
Move past this. You cannot have a utopia which is divided on any level except that of the individuals which make up the whole. We would have individual homes, families, lives and ideas. Those which advance the condition of Humanity would have access to more tools to do just that. Those who choose to do nothing can still enjoy a relatively stress free life without need to go hungry or unsheltered. Humans are not naturally lazy. Anyone thinking that somebody else should do things for them like dress them, raise their children or clean their homes are the lazy ones. There would be none of that.
Like Bluce mentioned earlier, much of this utopian world would come as a result of technology. Labor saving tools, robotic equipment performing tasks which endanger human lives (like mining or working around dangerous chemicals). The elimination of money insures that jobs get done without regard to "the bottom line". The product would be shared amongst all, not sold. United Humanity can have no borders.
