Some interesting theories about human and pigs :

Human that don't know how to enjoy = pigs that work
Men = eat + sleep + earn money Pigs = eat + sleep Hence, Men = Pigs + earn money therefore, Men - earn money = Pigs in other words,
Men that don't earn money = Pigs

Women = eat + sleep + spend Pigs = eat + sleep Hence, Women = Pigs + spend therefore, Women - spend = Pigs In other words,
Women that don't spend = Pigs
Summary: Men earn money not to let women become pigs! Women spend not to let men become pigs! Men + Women = 2 Pigs Wish all the pigs happy forever.
