Answer:
Mercantilism.
Explanation:
Mercantilism is a set of ideas, a system which was quite popular in Europe in the 17th and 18th century.
Some of its basic principles are:
- increasing export while decreasing import
- which should enable accumulation of capital in the form of gold and silver
- strong agriculture that would decrease the need for import
- using colonies for gaining cheap resources and for selling the final products.
Many of late-18th century philosophers and economists criticized mercantilism pointing out its flaws and limits, so today it is considered an outdated system.
