Multi-national companies use developing countries as their base ground for manufacturers or we can say for labor forces. Cheap labor, cheap land, and cost-effective transportation are some key points that make developing countries a hot cake for multinational companies. All the telecom companies in Bangladesh are owned by foreign companies.
Because it is considered a very good land for the development of multinational companies so that the company continues to look at such countries to get more profits with less capital. And actually it is part of a very good business strategy because the target of each company itself is to market as many products as possible and get the largest possible profit with very simple capital. This is a very mature calculation because when the company has no competition with local companies there, then at least they can dominate the market a bit for this.
