Why are men larger than women?

It makes no evolutionary sense for women to be smaller because everything from birthing children to surviving predators would be easier with we were the same size as men. So why are we smaller?

Because men have staved women of food for untold generations to ensure their own survival. A smaller body means women can survive with less food and have more to share with their children because with men around both mother and child are going to get less of everything. So smaller women were more likely to survive time of famine and therefore we have evolved to become smaller so we can survive men’s greed.
