High-income countries are to advanced economic productivity as lower-middle-income countries are to what level of productivity?

High-income countries are known for their advanced economic productivity, meaning they produce a lot of goods and services efficiently and have strong economies. In contrast, lower-middle-income countries generally have a lower level of productivity, often characterized by less advanced technology and fewer resources. These countries might rely more on agriculture or simple manufacturing rather than high-tech industries. For example, a country like Bangladesh, which is considered a lower-middle-income country, often has lower productivity levels compared to wealthier nations, as it focuses on textile production rather than advanced electronics. Thus, while high-income countries lead in productivity, lower-middle-income countries typically have much room to grow and improve their economic output.
