Women know how to manage problems better and resolve them in a more effective way than men. On the another hand, they are mothers, and I presume they don't like to play as soldiers, so there would be fewer or no wars. It's possible that different countries would help one another so that the contrast between the richest and poorest would be less than now. Medical research would be better, and it's possible that scientific research would be too. I think all this would be better, but I could be wrong.
