Why did multinational corporations want to acquire Country Z's enterprises?
Because Country Z's underdeveloped market was too tempting.
Country Z's population was not only large, but it also had an alarming consumer potential as well as thousands of years worth of brilliant cultural heritage. These caused foreign investors to crave the acquiring of Country Z. Furthermore, the people of Country Z were hardworking, pragmatic, could create value, and were shockingly effective.
For example: when the people of Country Z opened a hair salon in Italy, there was no one who could compare to them.
An Italian-owned hair salon would have 8 fixed working hours a day. Past the working time, they would reject customers.
However, a hair salon opened by the people of Country Z would operate 24/7, non-stop. They would also adopt a three-shift system to improve flexibility and effectiveness.
