Explanation:
The US and Western Europe are in the category of more developed countries. They all have strong economies, highly industrialized, and very large production of goods and services. The fact that they have very large production of goods and services means that they have high Gross Domestic Product (GDP). The GDP is an excellent parameter when it comes to showing the strength and development of an economy, and a high GDP that constantly becomes higher and higher each year means that an economy is very strong and develops well.
