The German Democratic Republic had state-run universal daycare from ages 0 to 18 (Krippe, Garten, POS, FDJ). It was commonly seen as a bad thing by western societies, because it gave ample opportunity to indoctrinate.

PS: POS and FDJ are not really daycare but school and youth org, but they provided services exceeding what we connect with those ideas.

If you are a child living under parents, your parents also have ample opportunity to indoctrinate. There is zero viewpoint diversity.

One wonders how much of this viewpoint was itself indoctrinated.
