WWI Britain or France or WWII Russia or Berlin? Sure. WWII America? No. We thankfully did not suffer so many casualties as to cause a huge demographic imbalance....ie not enough men died to greatly drive up the value of men. The reason the marriage and birth rates were so high after the war was pent up demand from 4 years of lots of young men being away fighting.
Hey, everyone! I called it! A_perfect_lady has now officially repeated the hateful utterance made by Hillary Clinton: "Millions of men die in war - women most affected!"
Or rather the converse: If men want to improve their dating / mating chances, all they have to do is allow themselves to be decimated; then the survivors will face less competition and therefore have better chances with the otherwise hypergamous women!
Or, in other words: If you want to curb female hypergamy, just kill off a couple of million men! Easy-peasy!
