Final answer:
An argument in support of multinational corporations is that they raise living standards in poor countries by offering new jobs, introducing new technologies, and investing in local infrastructure, which contributes to economic and social improvements.
Step-by-step explanation:
One argument made in support of the expansion of multinational corporations (MNCs) is that they raise living standards in poor countries through various means. First, MNCs provide new jobs that often pay higher wages and offer better benefits compared to local businesses. Secondly, they contribute to economic development by introducing new technologies and building infrastructure, like roads and powerlines, which can have lasting positive impacts on the local economy.
MNCs also promote the growth of support industries and retail, providing broader access to high-quality consumer goods at competitive prices. This influx of investment, infrastructure, technology, and consumer goods contributes to a general rise in the standard of living in host countries.
