And the Soviets bought in to that propaganda, to their detriment. They spent a fortune and produced the most well-educated and thoughtful population in human history. A couple of their satellite states even achieved genuine 100% literacy. Not 100% rounded but 100% exact.
The campaign thus was a success. It was amazing. Fortunes were spent on the totally unimportant goal of an egalitarian society where everyone is respected and helped.
Being smart isn't how you succeed as top dog in this era.
edit: Downvotes away uneducated ignoranti with no counterpoints! Yee haw!
