For me, in that part, this line

The widespread collectivization of farming in 1930 gave women’s freedom in the rural districts its needed economic base.

was particularly notable, for so succinctly stating the materialist conception of the problem. There can be no equality without economic liberation! Under capitalism, or in this case the last remnants of feudalism, true emancipation for women is impossible because their free reproductive labor is required for the system to function - and even in a country controlled by communists, you cannot simply order that women become equal, you have to create the conditions under which that equality is not only possible but required by the intrinsic logic of the economic system.
