Answer: high availability of cheaper labor
Explanation:
Multinational companies such as Apple and Nike have their manufacturing basis is emerging markets and developing countries and this is because of the profits they stand to make by accessing labor at cheaper rates in these countries.
As these countries are only emerging, they will not have the income levels of developed countries and so their citizens will be willing to collect meagre salaries to get by. This is the case in most African and a lot of South East Asian countries.
