Markets began to saturate beyond a point of trade. Communication inventions changed the demand matrix of the trade with countries. There began to flow news about better products, better lifestyle, better raw materials and better finished goods. Automobiles was a major invention in those times and it began to create desires in the mind of normal labourers who also wanted a piece of the overall success that was visible but limited though to the rich and accumulated. Economists also started to invent new ideas about economic progress and to suggest ways of experimenting the economy with infusing new ideas about partnering with other countries selectively to introduce new and productive materials that were not seen before. Adam Smith as an economist instilled all his ideas about economy in his book ‘Wealth of Nations’ and the book had a massive success which opened the minds of many more economists and suddenly raised a lot of questions about new possibilities and the risks associated with those possibilities. As mercantilists believed that a massive population of UK would help in using every inch of the soil for agriculture, Adam Smith came up with a proposition that massive population growth can outgrow the availability of resources. This thought gave rise to balance the internal resources with exchanging some with other countries so that they will not be depleted and can be sustained and nurtured.
