are you pig??

Human = eat + sleep + work + enjoy
Pigs = eat + sleep
Hence, Human = Pigs + work + enjoy
if, Human - enjoy = Pigs + work
in other words,
Human that don't know enjoy = pigs that work

Men = eat + sleep + earn money
Pigs = eat + sleep
Hence, Men = Pigs + earn money
if 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
if, 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.
