Donkey = eat + sleep

Therefore
Human = Donkey + work + enjoy
If, 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
If 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
If, 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 Donkeys

And the Donkeys lived happily ever after



What a romance
