These are the three elements that are required for a place to achieve industrial growth. Most of the time, a place only has one or two of these elements, and the lack of the third one will determine much of their trade and other economic activities. For example, countries that have a large number of workers might focus on manufacturing, such as China.
I think the United States help Western European countries regain their economic strength in order to hold off the threat of communism by initiating the Marshall Plan.
