Give me a summary of Adam Smith's philosophy and beliefs.

Adam Smith was among the first philosophers to declare that wealth is created through productive labor, and that self-interest motivates people to put their resources to the best use. He argued that profits flowed from capital investments, and that capital gets directed to where the most profit can be made. Smith argued against mercantilism and was a major proponent of laissez-faire economic policies.

Explanation:

when a country suffers, for example, a drought period, the market product is affected for a low offer, in this case, potatoes; the government has to tax to the households, which have to give more money for the potatoes which they consume, that situation make them consume substitute goods even through loans, it could increase the financial market movement and the inflationary phenomena, the business has to increase salaries in order to the employees could buy a more expensive food (potatoes) and in order to inflation tha business had to buy expensive supplies in the factor market, while the rest of the world have to gain more money to consume the same amount of potatoes.
