This document discusses modern challenges faced by developed and developing countries. Developed countries tend to have strong economies, educated populations with good healthcare access, and consume a large share of global resources. Developing countries have weaker economies with widespread poverty, lower education levels, and less healthcare access. Population growth and environmental degradation also present challenges. Other issues include immigration, technology gaps, ethnic/religious conflicts, and poverty. However, some argue that free market economies can help developing countries increase wealth and political freedoms, as seen in Asian Tiger economies like Taiwan and South Korea.
