Globally, women make up 40% of the agricultural workforce. One out of five farms are headed by women. Women are and always have been a major force in food production. With polygyny being nearly universal until recent times (and still practiced in various forms basically everywhere today), it seems unlikely to me that whatever random loot the local tough is likely to feel like spreading among his partners (assuming he comes back home now and then when he’s board of raping) is going to make a huge difference- at least not compared with other things a guy might do to contribute to a household.
In the meantime, how did the leopard get his spots?
