The document presents three equations comparing humans, men, and women to donkeys. The first equation shows that humans equal donkeys plus work plus enjoy, and therefore humans without enjoyment equal donkeys that work. The second equation shows that men equal donkeys plus earning money, and therefore men without earning money equal donkeys. The third equation shows that women equal donkeys plus spending, and therefore women without spending equal donkeys. In conclusion, it states that men without earning money equal women without spending, so men earn money and women spend money to avoid becoming donkeys, and together they equal two donkeys living happily together.
