It is an economic rule stating that production is where
demand originated. When a person creates
a product and that gets sold, the person gets paid. Once he gets paid he can then demand other
goods and services by paying. This was
developed by Jean-Baptiste Say who believed in free enterprise and was inspired
by Adam Smith. He added that value of the products we buy depends on the value
of the products we make. So it means you
get what you put in.
