A truly educated society will recognize this, and will mobilize to ensure that nobody is left behind. My concept of socialism also includes the collective production and distribution of goods. So, what we have is a system where people govern themselves and are allowed to help others directly. No government is needed to govern the people, because people can and will do that themselves. Farmers grow crops and store them in a public place.
Carpenters build houses.
Teachers educate others freely. Basically, people do what they normally would, but for free. Anything they need is provided at no cost. Money is not needed. Government is not needed.
