1947-1991
Cold War and Red Scare 2.0
Everyone is on edge, elites, professors and college students are seen as possibly compromised because of communism. Disinterest in them as attractive partners fall, even the elites, professors and students themselves become cautious of partners. This is compounded by lesson learned from great depression thus reducing partners and possible offspring to keep wealth stable.
>1955-1975Vietnam War
New generation of the uneducated once more are sent to war. This time though the survivors do not become war hero chads as public opinion slowly sees them as puppets for modern imperialism. Counter culture hippie movement also decreased the attractiveness of war time heroes.
Basically world war 1&2 caused the steep increase of uneducated men become preferred partners. Afterwards the trend of uneducated men having more partners remained because college educated men loss out on peak attractiveness on three different fronts. Only Vietnam set uneducated men back and that was only briefly.
