If you look at this excerpt from Friedrich Engels’s “Communist Confession of Faith” you’ll see a lovely section about child rearing and education.
Children will educated at the expense of the state.
Children will be educated by state institutions as soon as they can do without maternal care.
Get the kids indoctrinated early. Make them faithful servants of the machine as early as possible.
This is why stat education of any kind is a horrible idea. Communists are for it. It’s about power.
