Human & Donkey

Human = eat + sleep + work + enjoy 
Donkey = eat + sleep 
Therefore, 
Human = Donkey + work + enjoy  
So, Human - enjoy = Donkey + work 
In other words, 
Human that don't know enjoy = Donkey that work  
****************************************** 
Men = eat + sleep + earn money  
Donkeys = eat + sleep 
Therefore, 
Men = Donkeys + earn money 
So, Men - earn money = Donkeys 
In other words, 
Men that don't earn money = Donkeys  
****************************************** 
Women = eat + sleep + spend 
Donkeys = eat + sleep 
Therefore, 
Women = Donkeys + spend 
So, Women - spend = Donkeys  
In other words, 
Women that don't spend = Donkeys 
****************************************** 
To Conclude: 
* Men earn money not to let women become Donkeys!  
* Women spend not to let men become Donkeys! 
* Man + Woman = 2 Human!
