That brings up a theoretical question that has NEVER been sufficiently explained. Where does wealth come from and how can an entire country possibly get wealthier all at once. Adam Smith didn't get it.
A very very good question; one of the best questions to be every asked on FR.
At the root of all true wealth are manufactured goods. Those who are invested in the manufacturing of goods are the true wealth creators of the world--and this includes food products too. Whatever else you produce or provide-- news, entertainment,novels, poetry, education,marriage counseling, attorney services, theoretical physics research, online stores, brick&mortar stores,dating websites, porn.. ..the chain always ends in your ability to buy a manufactured product.
