Cory is working on a global marketing assessment team looking out well into the future to help determine the most attractive market areas around the world. He is evaluating market sizes and growth rates. He knows population will grow, he should consider:

A. countries with high purchasing power today may not continue to show the same growth in the future
B. the US and Western Europe will have dramatic increases in population growth leading to overcrowding.
C. the middle class in India will continue to shrink as the rich get richer and the poor get poorer.
D. urban population centers will become increasing unattractive and the rural areas will experience major growth in population.
E. All of the above.

Even if during the past decade the world's major economies have been the same -The U.S., Japan, China, Russia, and Germany- it does not necessarily mean the scenario will not change for the next one hundred years. Some other countries like Saudi Arabia, Switzerland, Belize, Luxembourg, and Australia have started to show signs of increasing development that could turn the worldwide economy into a new direction. The last five (5) countries are reported as being the top nations with the highest purchasing power for 2018.
