Is reverse hypergamy becoming more common than we think? Does anyone have any data to show whether or not these marriages tend to fail or succeed? Also, is it possible that hypergamy, in the dictionary definition of the word, is caused by social stratification more than "female nature"? I've read that females bring in about 60% of calories or more in hunter-gatherer societies, making them the primary bread-winners.
